Answer:

- 1 < x ≤ 6

Step-by-step explanation:

The open circle at x = - 1 indicates that x cannot equal - 1

The closed circle at x = 6 indicates that x can equal 6

- 1 is on the left of the graph and 6 on the right, thus values of x are between - 1 and 6, that is

- 1 < x ≤ 6

So you reversed the subtraction a bit; the equation you're gonna be solving is $3x^2+8x-7-(5x^2+2x-11)$ .

First step ya gonna do is to reverse the + and - symbols in the trinomial thats in the parentheses so your equation looks like $3x^2+8x-7-5x^2-2x+11$

Now just combine like terms and your answer should be $-2x^2+6x+4$
