x^{2} + 8 x - 20 = 0

x = 2, x = - 10

Solution steps

x^{2} + 8 x - 20 = 0

Move

20

to the right side

x^{2} + 8 x = 20

Rewrite in the form

(x + a)^{2} = b

(x + 4)^{2} = 36

For

the solutions are

f (x) = a, - a

Solve

x + 4 = 36 : x = 2

Solve

x + 4 = - 36 : x = - 10

The solutions to the quadratic equation are:

x = 2, x = - 10

x^{2} + 3 x = 0

6 x^{2} - 24 x + 18 = 0

2 x^{2} + 8 x - 3

3 + x = x^{2} + 3 x

x^{2} - x - 6 = 0
