Ax^{2}+Bx+C=0
Multiply 0 and 7 to get 0.
Ax^{2}+C=-Bx
Subtract Bx from both sides. Anything subtracted from zero gives its negation.
Ax^{2}=-Bx-C
Subtract C from both sides.
x^{2}A=-Bx-C
The equation is in standard form.
\frac{x^{2}A}{x^{2}}=\frac{-Bx-C}{x^{2}}
Divide both sides by x^{2}.
A=\frac{-Bx-C}{x^{2}}
Dividing by x^{2} undoes the multiplication by x^{2}.
A=-\frac{Bx+C}{x^{2}}
Divide -Bx-C by x^{2}.
Ax^{2}+Bx+C=0
Multiply 0 and 7 to get 0.
Bx+C=-Ax^{2}
