Which of the following best describes the expression 9(x + 7)? a. the sum of constant factors 9 and x + 7 b. the product of constant factors 9 and x + 7 c. the product of a constant factor 9 and a 2-term factor x + 7 d. the sum of a constant factor 9 and a 2-term factor x + 7

C. The product of a constant factor 9 and a 2-term factor x + 7 .

Step-by-step explanation:

Given  :  9(x + 7).

To find : Which of the following best describes the expression .

Solution : We have given that 9(x + 7)

We can see it is a product of 9 and (x+7)

The best description for expression is

Therefore, C. The product of a constant factor 9 and a 2-term factor x + 7 .

answer: answer

step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
