The factors of a polynomial function are the zeros of the function

It is true that x - 3 is a factor of m(x) = x^3 - x^2 - 5x - 3

<h3>How to show why the x - 3 is a factor</h3>

The function is given as:

m(x) = x^3 - x^2 - 5x - 3

The factor is given as:

x - 3

Set the factor to 0

x - 3 = 0

Solve for x

x = 3

Substitute 3 for x in the function

m(3) = 3^3 - 3^2 - 5(3) - 3

Evaluate

m(3) =0

Since the value of m(3) is 0, then x - 3 is a factor of m(x) = x^3 - x^2 - 5x - 3

Multiply (x - 4)(x - 3)<br> PLZZZ get it RIGHT, SHOW YOUR WORK,AND NO LINKS PLZ!
Pepsi [2]

Answer:

b

Step-by-step explanation:

(x - 4) (x - 3)

x^2 - 3x - 4x + 12 (you distribute x in (x-4) to each of the terms x and -3 and multiply them. x*x is x^2 and x*(-3) is -3x. Then, you distribute -4 in (x-4) to  each of the terms x and -3 and multiply them. -4*x is -4x and -4*-3 is 12)

x^2 - 7x + 12 (B)

-2+4(-x+4)=10 using distributive property and collecting like terms
stich3 [128]

Answer:

<h2>x = 1</h2>

Step-by-step explanation:

-2+4(-x+4)=10\qquad\text{use the distributive property:}\ a(b+c)=ab+ac\\\\-2+(4)(-x)+(4)(4)=10\\\\-2-4x+16=10\qquad\text{combine like terms}\\\\-4x+(-2+16)=10\\\\-4x+14=10\qquad\text{subtract 14 from both sides}\\\\-4x+14-14=10-14\\\\-4x=-4\qquad\text{divide both sides by (-4)}\\\\\dfrac{-4x}{-4}=\dfrac{-4}{-4}\\\\x=1

What is the product?<br><br> −5⋅(−3)⋅(−8)<br> A.-120<br> B.-16<br> C.16<br> D.120
Paha777 [63]

The product of the given expression is -120. Option A is correct

<h3>Product of negative numbers.</h3>

Given the expression below as shown;

−5⋅(−3)⋅(−8)

Since the product of two negative number is equal to positive, then;

−5⋅(−3)⋅(−8) = -8(5*3)

Simplify the result to have:

-8 * 15

find the final product

-8 * 15 = -8(5+10)

-8 * 15 = -40 - 80

-8 * 15 = -120

Hence the product of the given expression is -120
