2x^{2}+mx-7x-2m+2=0
Use the distributive property to multiply m-7 by x.
mx-7x-2m+2=-2x^{2}
Subtract 2x^{2} from both sides. Anything subtracted from zero gives its negation.
mx-2m+2=-2x^{2}+7x
Add 7x to both sides.
mx-2m=-2x^{2}+7x-2
Subtract 2 from both sides.
\left(x-2\right)m=-2x^{2}+7x-2
Combine all terms containing m.
\frac{\left(x-2\right)m}{x-2}=\frac{-2x^{2}+7x-2}{x-2}
Divide both sides by x-2.
m=\frac{-2x^{2}+7x-2}{x-2}
Dividing by x-2 undoes the multiplication by x-2.
