Answer: -12 but could be wrong
Step-by-step explanation:
I don't know that format but I'm going to take a guess.
x^2 +2x - 8 -(2x+8) then plug in x=2
x^2 + 2x - 8 - 2x - 8
x^2 -16
= 2^2 - 16 = -12
I wrote the steps down, hopefully you understand them and the answer is on the lower right corner.
7/5 x 7/1 = 49/5 or 9 4/5
