Question

(x+20) (2x+1) (x-1) ASAP Quick before tomorrow

Answer 1

Answer:

$(x + 20)(2 x + 1)(x - 1 )\\ = > x(2 x + 1)20(2 x + 1)(x - 1) \\ = > ({2x}^{2} + x + 4 0x + 20)(x - 1) \\ = > x({2x}^{2} + x + 4 0x + 20) - 1({2x}^{2} + x + 4 0x + 20)$

Answer 2

(x + 20) (2x + 1) (x − 1)

[ x(2x + 1) + 20(2x + 1) ] (x − 1)

(2x² + x + 40x + 20) (x − 1)

x(2x² + x + 40x + 20) − 1(2x² + x + 40x + 20)

2x³ + x² + 40x² + 20x − 2x² - x - 40x - 20

2x³ + 39x² - 21x - 20
