- 2 x^{2} = 8

x = 2 i, x = - 2 i

Solution steps

- 2 x^{2} = 8

Divide both sides by

- 2

x^{2} = - 4

For

x^{2} = f (a)

the solutions are

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

x = - 4, x = - - 4

- 4 = 2 i

- - 4 = - 2 i

x = 2 i, x = - 2 i

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

k^{2} - 11 = 89 - k^{2}

12 x^{2} - 48 x - 5 = 0

x^{2} + 4 x + 8 = 0

3 x^{2} - 48 x + 144 = 0
