mx^{2}-2x^{2}+\left(m+3\right)x-8=0
Use the distributive property to multiply m-2 by x^{2}.
mx^{2}-2x^{2}+mx+3x-8=0
Use the distributive property to multiply m+3 by x.
mx^{2}+mx+3x-8=2x^{2}
Add 2x^{2} to both sides. Anything plus zero gives itself.
mx^{2}+mx-8=2x^{2}-3x
Subtract 3x from both sides.
mx^{2}+mx=2x^{2}-3x+8
Add 8 to both sides.
\left(x^{2}+x\right)m=2x^{2}-3x+8
Combine all terms containing m.
\frac{\left(x^{2}+x\right)m}{x^{2}+x}=\frac{2x^{2}-3x+8}{x^{2}+x}
Divide both sides by x^{2}+x.
m=\frac{2x^{2}-3x+8}{x^{2}+x}
Dividing by x^{2}+x undoes the multiplication by x^{2}+x.
m=\frac{2x^{2}-3x+8}{x\left(x+1\right)}
Divide 2x^{2}-3x+8 by x^{2}+x.
