x^{2} + 8 x + 16 = 0

x = - 4

Solution steps

x^{2} + 8 x + 16 = 0

Move

16

to the right side

x^{2} + 8 x = - 16

Rewrite in the form

(x + a)^{2} = b

(x + 4)^{2} = 0

Solve

x + 4 = 0 : x = - 4

The solution to the quadratic equation is:

x = - 4

2 x^{2} - 50 x = 0

3 r^{2} - 8 = 6

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

3 x^{2} - 12 x + 12 = (x - 3)

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