x^{2} + 8 = - 1

x = 3 i, x = - 3 i

Solution steps

x^{2} + 8 = - 1

Move

8

to the right side

x^{2} = - 9

For

x^{2} = f (a)

the solutions are

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

x = - 9, x = - - 9

- 9 = 3 i

- - 9 = - 3 i

x = 3 i, x = - 3 i

x, 12 x^{2} - 3 y^{2} + 12 z^{2} + 6 x = 15

0.534 (0.5 - x)^{2} = x^{2}

x, z = x^{2} + x y + y^{2} - 3 x - 6 y

5 p^{2} - 7 p + 3 = p^{2}

x, f (x^{2}) = 3 (x^{2}) + 2
