x+7-x+1=8

x – x cancel out,

7+1=8

8=8 correct.

“if it were x+7+x+1 would it then be 8x^2?”

no, it would not. it would only be squared if the x’s were being multiplied. like,

x*x*8 = 8x^2

x*x+8 = x^2 + 8

yes think of it like this you have a x and you have a -x they can cancel out then you have a 7+1 which is 8. so you are left with 8=8. so this statement is ture for all real numbers.
