Bx^{2}-\left(Bx-2x\right)+2=0
Use the distributive property to multiply B-2 by x.
Bx^{2}-Bx+2x+2=0
To find the opposite of Bx-2x, find the opposite of each term.
Bx^{2}-Bx+2=-2x
Subtract 2x from both sides. Anything subtracted from zero gives its negation.
Bx^{2}-Bx=-2x-2
Subtract 2 from both sides.
\left(x^{2}-x\right)B=-2x-2
Combine all terms containing B.
\frac{\left(x^{2}-x\right)B}{x^{2}-x}=\frac{-2x-2}{x^{2}-x}
Divide both sides by x^{2}-x.
B=\frac{-2x-2}{x^{2}-x}
Dividing by x^{2}-x undoes the multiplication by x^{2}-x.
B=-\frac{2\left(x+1\right)}{x\left(x-1\right)}
Divide -2x-2 by x^{2}-x.
