Divide both sides by 55.

{x}^{2}=-\frac{500}{5}x2=−5500

2

Simplify \frac{500}{5}5500 to 100100.

{x}^{2}=-100x2=−100

3

Take the square root of both sides.

x=\pm \sqrt{-100}x=±√−100

4

Simplify \sqrt{-100}√−100 to \sqrt{100}\imath√100ı.

x=\pm \sqrt{100}\imathx=±√100ı

5

Since 10\times 10=10010×10=100, the square root of 100100 is 1010.
