x^{2} + 2 x = 15

x = 3, x = - 5

Solution steps

x^{2} + 2 x = 15

Rewrite in the form

(x + a)^{2} = b

(x + 1)^{2} = 16

For

the solutions are

f (x) = a, - a

Solve

x + 1 = 16 : x = 3

Solve

x + 1 = - 16 : x = - 5

The solutions to the quadratic equation are:

x = 3, x = - 5

0 = - 5 x^{2} + 3 x - 2

f^{2} + 2 f - 8 = 0

- 5 x^{2} + 600 x - 18000 = 0

(3 x + 2)^{2} = 8

15 x^{2} + 16 x - 15 = 0
