x^{2} + 6 x - 55 = 0

x = 5, x = - 11

Solution steps

x^{2} + 6 x - 55 = 0

Move

55

to the right side

x^{2} + 6 x = 55

Rewrite in the form

(x + a)^{2} = b

(x + 3)^{2} = 64

For

the solutions are

f (x) = a, - a

Solve

x + 3 = 64 : x = 5

Solve

x + 3 = - 64 : x = - 11

The solutions to the quadratic equation are:

x = 5, x = - 11

2 x^{2} - 7 = 11

x^{2} + 10 x + 1

x^{2} + 10 x + 5

y^{2} - 6 y = 27

- 2 x^{2} + 16 x - 18 = 0
