Answer by Alan3354(30993)   (Show Source): You can put this solution on YOUR website!(x+2z)(2x+z)..?? How to solve the given above problem using (a+b)(a-b) identity and 4ab=(a+b)^2 - (a-b)^2 identity...?? -------------- There's nothing to solve. Equations are solved. ---- (x+2z)(2x+z)..?? = x*(2x+z) + 2z*(2x+z) = = ------------- How to solve the given above problem using (a+b)(a-b) identity and 4ab=(a+b)^2 - (a-b)^2 identity...?? -------- (x+2z)(2x+z) is not a sum and difference, like (a+b)(a-b)
