x^{2} + 6 x + 9 = 0

x = - 3

Solution steps

x^{2} + 6 x + 9 = 0

Move

9

to the right side

x^{2} + 6 x = - 9

Rewrite in the form

(x + a)^{2} = b

(x + 3)^{2} = 0

Solve

x + 3 = 0 : x = - 3

The solution to the quadratic equation is:

x = - 3

x, 9 x^{2} + 4 y^{2} + 36 x - 24 y + 72 = 0

x, 4 x^{2} - y^{2} + 2 z^{2} + 4 = 0

8 x^{2} + 12 x + 3 = 0

x^{2} + 6 x = 13

x^{2} + 6 x = 48
