x^{2} - 2 x - 5 = 0

x = 6 + 1, x = - 6 + 1

Decimal Notation

x = 3.44948 \dots, x = - 1.44948 \dots

Solution steps

x^{2} - 2 x - 5 = 0

Move

5

to the right side

x^{2} - 2 x = 5

Rewrite in the form

(x + a)^{2} = b

(x - 1)^{2} = 6

For

the solutions are

f (x) = a, - a

Solve

x - 1 = 6 : x = 6 + 1

Solve

x - 1 = - 6 : x = - 6 + 1

The solutions to the quadratic equation are:

x = 6 + 1, x = - 6 + 1

x^{2} - 6 x - 16 = 0

24 x - 36 x^{2} = 0

x^{2} - x - 30 = 0

6 x (x - 2) = - 2 (x - 2)

x^{2} + 8 x + 7 = 0
