What is the result when 2x 2 + 3x - 1 is subtracted from 4x 2+ 7x - 3?

Answers & Comments

Answer:

$-2x^2-4x+2$

Step-by-step explanation:

$> <img src=$

$-\left(4x^2+7x-3\right)=-4x^2-7x+3$ $=2x^2+3x-1-4x^2-7x+3$

$> add : <img src=$

$=2x^2-4x^2+3x-7x+2$ then, $\mathrm{Add\:similar\:elements:}\:2x^2-4x^2=-2x^2$

$=2x^2-4x^2+3x-7x+2$ $\mathrm{Add\:similar\:elements:}\:3x-7x=-4x$

$=-2x^2-4x+2$

Tilllastforever thanks
