Question

Multiply. (4x+6y)(x^2+3xy-4y^2)

Answer 1

Basically, you do the same concept as FOILing.
(4x + 6y)(x^2 + 3xy - 4y^2)
4x^3 + 12x^2y - 16xy^2 + 6x^2y + 18xy^2 - 24y^3
4x^3 + 18x^2y + 2xy^2 - 24y^3

Answer 2

multiply. you need to do six multiplication by the distributive law
when you get done you should have \(4 x^3+18 x^2 y+2 x y^2-24 y^3\)

Answer 3
