8 x^{2} = - 128

x = 4 i, x = - 4 i

Solution steps

8 x^{2} = - 128

Divide both sides by

8

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

y, x^{2} + y^{2} - 5 = 2 x y + y^{2} - 5

0 = 6 x^{2} - 7 x + 2

x^{2} + 6 = 8 x

x, x^{2} - 15 x = 0

9 x^{2} + 18 x - 27 = 0
