- 9 x^{2} = 72

x = 22 i, x = - 22 i

Solution steps

- 9 x^{2} = 72

Divide both sides by

- 9

x^{2} = - 8

For

x^{2} = f (a)

the solutions are

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

x = - 8, x = - - 8

- 8 = 22 i

- - 8 = - 22 i

x = 22 i, x = - 22 i

5 (x^{2} - 1) + 3 (x^{2} - 5) + 4 = 16

x^{2} + 2 x - 1 = 2 x

(2 x + 4) (3 x + 6) = a (x^{2} + b x + c)

x^{2} - 2 \cdot x - 3 = 0

4 (x + 1)^{2} = 18
