Question

simplify (3x^2+8x)(2x-3) b.(x+1)(x-2)(x+3)(x-4) only a genius can answer​

Answer 1

Answer:

a. 6x^3+7x^2-24x. and b. (x^2-x-2) ( x^2-x-12)

Answer 2

Answer:

a.

$(3x {}^{2} + 8x)(2x - 3) \\ = 6x {}^{3} + 16x {}^{2} - 9x {}^{2} - 24x \\ = 6 {x}^{3} + 7 x{}^{2} - 24x \\ answer$

b.

$(x + 1)(x - 2)(x + 3)(x - 4) \\ = (x {}^{2} - x - 2)(x {}^{2} - x - 12) \\ = x {}^{4} - x {}^{3} - 12 {x}^{2} - {x}^{3} + {x}^{2} + 12x - 2 {x}^{2} + 2x + 24 \\ = {x}^{4} - 2 {x}^{3} - 13 {x}^{2} + 14x + 24 \\ answer$
