- x^{2} = 81

x = 9 i, x = - 9 i

Solution steps

- x^{2} = 81

Divide both sides by

- 1

x^{2} = - 81

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

x = - 81, x = - - 81

- 81 = 9 i

- - 81 = - 9 i

x = 9 i, x = - 9 i

3 u^{2} = 30 u - 12

2 x^{2} + 3 = 35

0 = - \frac{1}{7} x^{2} + 200 x

468 = 500 - 2 q^{2}

7^{2} = x^{2} + 5^{2}
