Question

9. Multiply:
(a) 2x2 - x + 3 by x-2​

Answer 1

Answer:

9x - 14 - $x^{2}$

Step-by-step explanation:

(2x2 - x + 3) x (x-2) = (4 -x + 3) x (x-2) = (7-x) x (x-2) = 7x - 14 -$x^{2}$ + 2x = 9x - 14 - $x^{2}$

$\sf⟹\:(2x^{2}-x+3) \: \times \:(x-2)$

$\sf⟹\:x(2x^{2}-x+3)-2(2x^{2}-x+3)$

$\sf⟹\:2x^{3}-x^{2}+3x-4x^{2}+2x-6$

$\sf⟹\:2x^{3}-x^{2}-4x^{2}+3x+2x-6$

$\tt\pink{⟹\:2x^{3}-5x^{2}+5x-6}$
