7 x^{2} = - 21

x = 3 i, x = - 3 i

Solution steps

7 x^{2} = - 21

Divide both sides by

7

x^{2} = - 3

For

x^{2} = f (a)

the solutions are

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

x = - 3, x = - - 3

- 3 = 3 i

- - 3 = - 3 i

x = 3 i, x = - 3 i

12 8^{\frac{1}{3}} \cdot 4^{\frac{1}{3}}

- \frac{\frac{5}{3}}{( - \frac{1}{8} )}

- \frac{2}{3} x < - 8

x^{2} - 8 x = 9

(53 + 15) \cdot (35 - 15)
