9 x^{2} + 144 = 0

x = 4 i, x = - 4 i

Solution steps

9 x^{2} + 144 = 0

Move

144

to the right side

9 x^{2} = - 144

Divide both sides by

9

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

x, x^{2} - y^{2} + z^{2} - 2 x + 2 y + 4 z + 2 = 0

(x + 8)^{2} = x^{2} + (x + 7)^{2}

z^{2} + 16 = 10 z

7 x^{2} - 28 x + 1 = 0

x^{2} + 14 x - 15 = 0
