Place the indicated product in the proper location on the grid. Write your answer in descending powers of x. (x^2 + 2x - 1)(x^2 + 2x + 5)
(x^2 + 2x - 1)(x^2 + 2x + 5) = x^4 + 2x^3 + 5x^2 + 2x^3 + 4x^2 + 10x - x^2 - 2x - 5; = x^4 + 4x^3 + 8x^2 + 8x - 5

Place the indicated product in the proper location on the grid. (3m^3 - 1/2y) (3m^3 - 1/2y)
Question

(3m^3 - 1/2y) (3m^3 - 1/2y)
= 3m^3*3m^3 - 1/2y*3m^2 - 3m^3*1/2y + (-1/2y)(-1/2y)
= 9m^6 - 3/2m^3y - 3/2m^3y + 1/4y^2
= 9m^6- 3m^3y + 1/4y^2
