(x + 2)^{2} = - 81

x = 9 i - 2, x = - 9 i - 2

Solution steps

(x + 2)^{2} = - 81

For

(g (x))^{2} = f (a)

the solutions are

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

Solve

x + 2 = - 81 : x = 9 i - 2

Solve

x + 2 = - - 81 : x = - 9 i - 2

The solutions to the quadratic equation are:

x = 9 i - 2, x = - 9 i - 2

(x - 7) = 10

\frac{4}{3} + \frac{1}{2}

- 4 216 x^{2} y^{2} z

\frac{6 - i}{5}

3 (2 x + 3) + 4 x + 2 = 21
