Answer:
[tex]x=0[/tex]
Step-by-step explanation:
[tex]x^2+4x-2x=x^2+x[/tex]
Combine like terms.
[tex]x^2+2x=x^2+x[/tex]
Add [tex]-x^2[/tex] and [tex]-2x[/tex] on both sides.
[tex]x^2+2x-x^2-2x=x^2+x-x^2-2x[/tex]
[tex]0=x-2x[/tex]
[tex]0=-1x[/tex]
Divide both sides by [tex]-1[/tex].
[tex]\frac{0}{-1} =\frac{-1x}{-1}[/tex]
[tex]0=x[/tex]
