- 4 x^{2} = - 64

x = 4, x = - 4

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

- 16 = - 4

x = 4, x = - 4

w^{2} - 5 w - 14 = 0

x^{2} - 13 x - 7 = 0

(\frac{2}{3}) (t^{2} - 1) = 12

\frac{x}{3} - 1 + \frac{x ^{2}}{2} = - 2 x^{2} + x - \frac{7}{6}

6 a^{2} + 5 a - 4 = 2
