x^{2}\pi =0
Swap sides so that all variable terms are on the left hand side.
\frac{\pi x^{2}}{\pi }=\frac{0}{\pi }
Divide both sides by \pi .
x^{2}=\frac{0}{\pi }
Dividing by \pi undoes the multiplication by \pi .
x^{2}=0
Divide 0 by \pi .
x=0 x=0
Take the square root of both sides of the equation.
x=0
The equation is now solved. Solutions are the same.
x^{2}\pi =0
Swap sides so that all variable terms are on the left hand side.
\pi x^{2}=0
Quadratic equations like this one, with an x^{2} term but no x term, can still be solved using the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}, once they are put in standard form: ax^{2}+bx+c=0.
x=\frac{0±\sqrt{0^{2}}}{2\pi }
This equation is in standard form: ax^{2}+bx+c=0. Substitute \pi for a, 0 for b, and 0 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±0}{2\pi }
Take the square root of 0^{2}.
x=\frac{0}{2\pi }
Multiply 2 times \pi .
x=0
Divide 0 by 2\pi .
