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

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

Decimal Notation

x = 8.24264 \dots, x = - 0.24264 \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

2 x^{2} - 3 x + 21 = a (x - b)^{2} + c

0.000015 (x + 100)^{2} = 0.225375

5 y + 2 y^{2} = 12

x, f (x + 3) = 4 x^{2} + 4 x - 3

x^{2} + 2 x - 48 = (x + 8)
