X=2 or -7(answer choice A)

A) 2, -7

This is because you can view each (x-2) and (x+7) as a number. Thinking like this you have two numbers multiplied together to give you 0. The only way to multiply two numbers and get 0 is if either one or both of the numbers are 0. (As anything times 0 is 0.) So:

(x - 2) could be 0   or   (x + 7) could be 0

Mathematically:

x - 2 = 0           and            x+ 7 =0
   +2    +2                               -7   -7
x = 2                                  x = -7

Simplify the expression 9t^2+14-17t+6t-8t^2
slamgirl [31]

Answer:

t^2 - 11t + 14

Step-by-step explanation:

Begin by grouping like terms in 9t^2+14-17t+6t-8t^2.

First we have 9t^2 - 8t^2, or 1t^2.

Next, we have -17t + 6t, or -11t.

Last, we have the constant term 14.

The expression in simplified form is t^2 - 11t + 14.
