4 x^{2} = - 64

x = 4 i, x = - 4 i

Solution steps

4 x^{2} = - 64

Divide both sides by

4

x^{2} = - 16

For

x^{2} = f (a)

the solutions are

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

x = - 16, x = - - 16

- 16 = 4 i

- - 16 = - 4 i

x = 4 i, x = - 4 i

(13 x - 11) (13 x - 15) = 330

x^{2} - 6 x + 7 = 4 x

24 t^{2} - 216 t + 480 = 0

13 x - 1.65 x^{2} = 23.8

\frac{5}{4} x^{2} + 7 x + 9 = 0
