Answer 1

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 $-2x^2+6x+4$
