(x + 8)^{2} - 4 = - 20

x = 4 i - 8, x = - 4 i - 8

Solution steps

(x + 8)^{2} - 4 = - 20

Move

4

to the right side

(x + 8)^{2} = - 16

For

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

the solutions are

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

Solve

x + 8 = - 16 : x = 4 i - 8

Solve

x + 8 = - - 16 : x = - 4 i - 8

The solutions to the quadratic equation are:

x = 4 i - 8, x = - 4 i - 8

x^{2} - \frac{9}{16} = 0

1200 - 1.5 x^{2} = 200 + x^{2}

8 x^{2} - 200 = 0

(2 x - 1)^{2} - (x + 3)^{2} = 0

(x^{2} + 1) 2 - 5 x^{2} - 5 = 0
