x^{2} - 8 = - 2 x

x = 2, x = - 4

Solution steps

x^{2} - 8 = - 2 x

Move

8

to the right side

x^{2} = - 2 x + 8

Move

2 x

to the left side

x^{2} + 2 x = 8

Rewrite in the form

(x + a)^{2} = b

(x + 1)^{2} = 9

For

the solutions are

f (x) = a, - a

Solve

x + 1 = 9 : x = 2

Solve

x + 1 = - 9 : x = - 4

The solutions to the quadratic equation are:

x = 2, x = - 4

\frac{t ^{2}}{330} - \frac{t}{5} + 24 = 0

y^{2} - y - 4 = 0

x^{2} + 12 x + 36 = 6

5 x^{2} - 4 = 16

8 x^{2} + 22 x + 12 = 0
