4 x^{2} = 256

x = 8, x = - 8

Solution steps

4 x^{2} = 256

Divide both sides by

4

x^{2} = 64

For

x^{2} = f (a)

the solutions are

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

x = 64, x = - 64

64 = 8

- 64 = - 8

x = 8, x = - 8

0 = 3 x^{2} - 4 x - 5

m^{2} - 5 m + 3 = 0

8 y^{2} + 8 y + 2 = 0

s^{2} + 16 s + 65 = 0

(x - 4)^{2} - 28 = 8
