is that how you would like it?
ginny1029 said:… the printed version states minus 2x over x+2 on the right … OK. I understand it's x + 2 in the denominator.
This seems odd, to me, but I'll run with it.
It seems odd because the righthand side has two algebraic fractions with the same denominator. I'm wondering why they did not combine these two ratios into the single fraction -x/(x + 2).

ginny1029 said:… from x^2 = x^2 - 2x - 2x^2 + 4x get
x^2 = -x^2 + 2x …
