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

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)
