(5x - 4)(5x + 9)
= 5x*5x - 4*5x + 5x*9 - 4*9
= 25x^2 - 20x + 45x - 36
= 25x^2 + 25x - 36

(x + 4)^3
= (x + 4)(x + 4)(x + 4)
= (x^2 + 8x + 16)(x + 4)
= x^3 + 8x^2 + 16x + 4x^2 + 32x + 64
= x^3 + 12x^2 + 48x + 64

Select the difference of (8x^2 - 3x^3) - (2x^2 - 5x^3)
Weegy: (2x^2 - 3x^3) - (8x^2 - 5x^3) = (2x^2 - 3x^3) + (-8x^2 + 5x^3) = 2x^3 - 6x^2 User: Simplify the following expression. 2(8x + 2) Weegy: 2(8x + 2) = (2)(8x) + (2)(2) = 16x + 4 User: Select the product of (5x - 4)(5x + 9). (More)
