3 x^{2} = - 21

x = 7 i, x = - 7 i

Solution steps

3 x^{2} = - 21

Divide both sides by

3

x^{2} = - 7

For

x^{2} = f (a)

the solutions are

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

x = - 7, x = - - 7

- 7 = 7 i

- - 7 = - 7 i

x = 7 i, x = - 7 i

x^{2} - 3 x < 2 x^{2} - 5 x + 6

x^{3} - x^{2} - 9 x + 9

6 x + 7 = 3 x - 6

\frac{2 x - 20}{3} = 2 x
