Question

Simplify: (4x2 - 2x) - (-5x2 - 8x).​

Answer 1

Answer:

(4x^2 - 2x) - (-5x^2 - 8x)

= 4x^2 - 2x + 5x^2 + 8x.

= 4x^2 + 5x^2 - 2x + 8x.

= 9x^2 + 6x.

= 3x(3x + 2).

$\huge\underline\bold\red{AnswEr}$

4x^2–2x+5x^2+8x

9x^2+6x

If given equation is equals to zero,then

9x^2+6x=0

3x(3x+2)=0

Therefore 3x =0 or 3x+2=0

x=0 or x=-2/3
