Question 28396: Will you simplify this for me?
4y(2y^2-3y)-3y^2(y-4)
Answer by sdmmadam@yahoo.com(530) (Show Source): You can put this solution on YOUR website!
4y(2y^2-3y)-3y^2(y-4)
=8y^3-12y^2-3y^3+12y^2
=8y^3+(-12y^2-3y^3)+12y^2 by additive associativity
=8y^3+(-3y^3-12y^2)+12y^2 by additive commutativity
=(8y^3-3y^3)-12y^2+12y^2 by additive associativity
=5y^3+0 (using -a+a = 0 by additive inverse law)
=5y^3
