x^{2} - 6 x - 8 = 0

x = 17 + 3, x = - 17 + 3

Decimal Notation

x = 7.12310 \dots, x = - 1.12310 \dots

Solution steps

x^{2} - 6 x - 8 = 0

Move

8

to the right side

x^{2} - 6 x = 8

Rewrite in the form

(x + a)^{2} = b

(x - 3)^{2} = 17

For

the solutions are

f (x) = a, - a

Solve

x - 3 = 17 : x = 17 + 3

Solve

x - 3 = - 17 : x = - 17 + 3

The solutions to the quadratic equation are:

x = 17 + 3, x = - 17 + 3

x^{2} + 2 x - 99 = 0

4 v^{2} + 4 = 40

(32 - x)^{2} + (16 - x)^{2} = x^{2}

5 x^{2} + 40 x = - 75

x^{2} - x + \frac{1}{8} = 0
