3 x^{2} - 6 = - 18

x = 2 i, x = - 2 i

Solution steps

3 x^{2} - 6 = - 18

Move

6

to the right side

3 x^{2} = - 12

Divide both sides by

3

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

\frac{5}{9} (7 - 6 x) - \frac{3}{4} (3 - 15 x) = \frac{1}{12} (3 x - 5) - \frac{1}{2}

\frac{2 p + 2 q}{p + q}

- 8 x = 64

\frac{- 4 h}{h ( x + h + 6 ) ( x + 6 )}

\frac{n}{8} = \frac{9}{12}
