    try the difference of squares formula in reverse. its the same as FOILing but it results in a shortcut

    idk? im confused now...i guess I had to solve it it? in order to simplify it wouldnt I have to solve it?

    solve it means finding a solution to an equation simplifying means rewriting an expression if there is no equals sign its just an expression and there is nothing to solve for

    were you given a value of x ? or was this expression equal to something ?

    sorry it was as I posted in the question. i didnt mean to put the ^6 its just 6. but hmmm then i guess i should just leave it as it maybe? confusing, i must say

    yeah usually they just say "simplify" if there is no equation to solve for anything.

    could you confirm my answer on another one? (-8a3b4)2 5(-8)^2(a)^2(b^4)^2 5(64)(a^2)(b^8) 320(a^6)(b^8)
