Answer:
4x^3-26x^2+15x-3
Step-by-step explanation:
STEP 1:
Simplify 3/1
The equation at the end of step 1:
(4•(x3)-(26•(x2)+15x)-3
STEP 2:
The equation at the end of step 2:
(4 • (x3) - (2•13x2)+ 15x) - 3
STEP 3:
The equation at the end of step 3:
(22x3 - (2•13x2)+ 15x) - 3
STEP 4:
Checking for a perfect cube
4.1 4x3-26x2+15x-3 is not a perfect cube
Trying to factor by pulling out :
4.2 Factoring: 4x3-26x2+15x-3
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 15x-3
Group 2: 4x3-26x2
Pull out from each group separately :
Group 1: (5x-1) • (3)
Group 2: (2x-13) • (2x2)
Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.

4.3 Find roots (zeroes) of : F(x) = 4x3-26x2+15x-3
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above-mentioned tools. It would only find Rational Roots that are numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 4 and the Trailing Constant is -3.
The factor(s) are:
of the Leading Coefficient: 1,2,4
of the Trailing Constant: 1,3
Let us test...

Wen is factoring the polynomial, which has four terms. 6x3 – 12x2 7x – 14 6x2 (x – 2) 7(x – 2) Which is the completely factored form of his polynomial? (6x2 7) (x –2) (6x2 – 2) (x 7) (6x2 2) (x – 7) (6x2 – 7) (x 2).
The factorized form of the polynomial 6x³ – 12x² + 7x – 14 is (6x²+7)(x–2).
What is a factor?A factor of n is a number which when multiplied by another number gives us the number n.
In order to factorize the polynomial 6x³ – 12x² + 7x – 14, we need to take the common terms out of the given polynomial, therefore, the polynomial can be factorized as,
[tex]6x^3-12x^2+7x - 14 \\\\[/tex]
Taking the common term 6x² out from the first two terms, and then 7 from the next two terms, therefore, the polynomial can be written as
[tex]6x^3-12x^2+7x - 14 \\\\= 6x^2(x-2)+7(x-2)\\\\=(6x^2 +7)(x-2)[/tex]
Hence, the factorized form of the polynomial 6x³ – 12x² + 7x – 14 is (6x²+7)(x–2).

Evaluate 1/3 ( 9 - k ) using the distributive property
Answer:
3-[tex]\frac{1}{3}[/tex]k
Step-by-step explanation:
when using the distributive property multiply 1/3 into everything inside the parentheses.
So your first step is to multiply 1/3 to 9.
[tex]\frac{1}{3}[/tex] x [tex]\frac{9}{1}[/tex] keeping in mind that all numbers are divisible by one.
then you get your answer of [tex]\frac{9}{3}[/tex] which equals 3.
From there you want to distribute the [tex]\frac{1}{3}[/tex] into k but you don't know what "k" is so you'll have an answer of [tex]\frac{1}{3}[/tex]k meaning that k whatever it is. Is being multiplied by the [tex]\frac{1}{3}[/tex].
which shows the algebraic representation of the phrase and its value when n = 4.2?
“twenty-eight plus the product of five and a number”
28 minus 5 n; when n = 4.2 the value is 7
28 + 5 n; when n = 4.2 the value is 49
28 n minus 5; when n = 4.2 the value is 112.6
28 n + 5; when n = 4.2 the value is 122.6
Answer:
B is the answer because 28 + the product is n so it is B.

The members of a school club sold sweatshirts for $15 each. They made $960 in sales. The equation 15x = 960 can
be used to determine x, the total number of sweatshirts they sold.
Which number line best represents the total number of sweatshirts they sold?
Answer:
A
Step-by-step explanation:
15x = 960
so,
x = 960/15 = 64
they sold 64 sweatshirts.
the answers C and D are outright nonsense for this question. we are not dealing with inequalities or intervals, we have one point of solution for the problem : x = 64.

The product of the provided binomial numbers (9 t minus 4)(negative 9 t minus 4) is equal to the option B which is,
[tex]-81t^2+16[/tex]
What is the product?Product is the resultant number which is obtained by multiplying a number with another. Let a number a is multiplied by number b. Then the Product of these two number will be,
[tex]p=a\times b[/tex]
Here, (a, b) are the real numbers.
The binomial given in the problem are,
[tex](9t-4)\\(-9t-4)[/tex]
Let the product of the above function is p. Thus,
[tex]p=(9t-4)\times(-9t-4)[/tex]
To find the product of these two binomials, multiply the first term of first binomial with both the terms of the second binomial.
Similarly, multiply the second term of first binomial with both the terms of second binomial. Thus,
[tex]p=9t(-9t-4)-4(-9t-4)\\p=-81t^2-36t+36t+16\\p=-81t^2+16[/tex]
Thus, the product of the provided binomial numbers (9 t minus 4)(negative 9 t minus 4) is equal to the option B which is,

A laser pointer in the shape of a cylinder is 13 centimeters long with a radius of 1 centimeter. It has a cone tip with a height of 3 centimeters. What is the volume of the stylus? Express your answer in terms of π.
The volume of the cylindrical stylus having a conical tip will be V=14π [tex]cm^{3}[/tex]
What will be the volume of the stylus?It is given that
height of the cylindrical shape of the stylus h=13cm
radius of stylus r= 1cm
height of the conical tip of the stylus h=3cm
Now we know that the
The volume of the cylinder = [tex]\pi r^{2} h[/tex]
The volume of the cone = [tex]\dfrac{1}{3} \pi r^{2} h[/tex]
The total volume of the stylus = volume of the cylinder +volume of the cone
Total volume = [tex]\pi r^{2} h + \fdrac{1}{3} \pi r^{2} h[/tex]
now by putting the values
[tex]=\pi (13)(1)^{2} +\dfrac{1}{3} \pi (1)^{2} (3)[/tex]
