3 x^{2} - 9 = - 156

x = 7 i, x = - 7 i

Solution steps

3 x^{2} - 9 = - 156

Move

9

to the right side

3 x^{2} = - 147

Divide both sides by

3

x^{2} = - 49

For

x^{2} = f (a)

the solutions are

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

x = - 49, x = - - 49

- 49 = 7 i

- - 49 = - 7 i

x = 7 i, x = - 7 i

(\frac{48 - 8 y}{12}) + 2 y = 6

\frac{5 x + 21}{4} = \frac{x}{2}

lo g_{8} (512)

\frac{2 - 3 x}{7} \leq 2

\frac{3}{2} x - 5 > 4
