x^{2} + 4 x = 45

x = 5, x = - 9

Solution steps

x^{2} + 4 x = 45

Rewrite in the form

(x + a)^{2} = b

(x + 2)^{2} = 49

For

the solutions are

f (x) = a, - a

Solve

x + 2 = 49 : x = 5

Solve

x + 2 = - 49 : x = - 9

The solutions to the quadratic equation are:

x = 5, x = - 9

120%

x, 4 x - 2 = 8

0.84%

x, - 3 x = 15

x, x + 9 = 18 - 2 x
