Question 458309: It is determined that if one side of a whiteboard is x+8y inches, the other side should be x^2-5xy+8y^2 inches. Write an algebraic expression for the area of such whiteboard, simplify it, and include correct units with solution. Will someone please check this question:
(x+8y) (x^2-5xy+8y^2)
x^3-5x^2y + 8x^2y+8x^2y- 40xy^2+64y^3
x^3+3x^2y-32xy^2+64y^3 inches
thank you
