Question

Simplify:
19.(3x-4) (2x ²- 5x+1)-(2x-1)(3x + 7x - 5)​

Answer 1

Answer:

thee answer is $-34x^{2}+40x-9$

Step-by-step explanation:

Given,

$(3x-4) (2x^{2} -5x+1)-(2x-1)(3x^{2}+7x-5)$

therefore

$=(6x^{3} -15x^{2} +3x-8x^{2} +20x-4)\\= -[(6x^{3}-14x^{2} +10x-3x^{2} -7x+5)$

answer is

$= -34x^{2}+40x-9$
