x^{2} + 2 x = 80

x = 8, x = - 10

Solution steps

x^{2} + 2 x = 80

Rewrite in the form

(x + a)^{2} = b

(x + 1)^{2} = 81

For

the solutions are

f (x) = a, - a

Solve

x + 1 = 81 : x = 8

Solve

x + 1 = - 81 : x = - 10

The solutions to the quadratic equation are:

x = 8, x = - 10

x^{2} + 2 x = 15

- 24 = - 3 x^{2} - 6 x

27 x^{2} + 5 = 48 x

2 x^{2} - 6 x - 18 = 0

4 y^{2} - 12 y + 9 = 0
