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

x = 32 - 4, x = - 32 - 4

Decimal Notation

x = 0.24264 \dots, x = - 8.24264 \dots

Solution steps

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

Move

2

to the right side

x^{2} + 8 x = 2

Rewrite in the form

(x + a)^{2} = b

(x + 4)^{2} = 18

For

the solutions are

f (x) = a, - a

Solve

x + 4 = 18 : x = 32 - 4

Solve

x + 4 = - 18 : x = - 32 - 4

The solutions to the quadratic equation are:

x = 32 - 4, x = - 32 - 4

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

30 - 13 x - 15 x^{2} = 0

y = x^{2} - 7 x + 12, x

(x - 4)^{2} = - 8

2 x^{2} + 20 x = 6
