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

x = 2, x = - 4

Solution steps

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

Move

8

to the right side

x^{2} + 2 x = 8

Rewrite in the form

(x + a)^{2} = b

(x + 1)^{2} = 9

For

the solutions are

f (x) = a, - a

Solve

x + 1 = 9 : x = 2

Solve

x + 1 = - 9 : x = - 4

The solutions to the quadratic equation are:

x = 2, x = - 4

3 x^{2} - 7 = 5

7 k = 78 - k^{2}

12 x^{2} - 36 x = 0

x^{2} + x - 14 = 0

x^{2} + x - 16 = 0
