hello again I need confirmation on some questions please!
"Simplify each of the following fractions. If they are already simplified say so.
1) a^2-2ab+b^2/a-b[my answer was: already simplified]
2) a^2-2ab+b^2/a+b[my answer was: already simplified]
"Some students simplify 2x^2-32/x-4 as 2x-8.
Choose values of x to show that this is not true.Then simplify it correctly."
I answered: Any value of x proves them incorrect. my simplification was:2x+8
thanks for all your help!
