Question 40977: (3x-2)(5x to the second power +8x-2)
Answer by fractalier(6550)   (Show Source):
You can put this solution on YOUR website! For (3x - 2)(5x^2 + 8x - 2), we multiply every term in the first expression by every term in the second, kind of like a round-robin tournament, where everyone plays everyone else...so we get
(3x - 2)(5x^2 + 8x - 2) =
15x^3 + 24x^2 - 6x - 10x^2 - 16x + 4 =
15x^3 + 14x^2 - 22x + 4
