x^{2} + 12 x + 20 = 0

x = - 2, x = - 10

Solution steps

x^{2} + 12 x + 20 = 0

Move

20

to the right side

x^{2} + 12 x = - 20

Rewrite in the form

(x + a)^{2} = b

(x + 6)^{2} = 16

For

the solutions are

f (x) = a, - a

Solve

x + 6 = 16 : x = - 2

Solve

x + 6 = - 16 : x = - 10

The solutions to the quadratic equation are:

x = - 2, x = - 10

9 x^{2} - 12 x + 9 = 0

y, 9 x = y^{2} + 18

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

x^{2} + 16 x - 1 = 0

(n - 5)^{2} - 30 = 70
