x^{2} + 4 x - 45 = 0

x = 5, x = - 9

Solution steps

x^{2} + 4 x - 45 = 0

Move

45

to the right side

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

- 2 x^{2} - 6 x + 7 = 0

2 u^{2} - 5 u - 3 = 0

x, y = - 0.02 x^{2} + x + 2.6

4 x (x - 2) + 3 (x - 3) = - 3

x, y^{4} = (x + 2)^{2}
