x^{2} - 8 x = 12

x = 27 + 4, x = - 27 + 4

Decimal Notation

x = 9.29150 \dots, x = - 1.29150 \dots

Solution steps

x^{2} - 8 x = 12

Rewrite in the form

(x + a)^{2} = b

(x - 4)^{2} = 28

For

the solutions are

f (x) = a, - a

Solve

x - 4 = 28 : x = 27 + 4

Solve

x - 4 = - 28 : x = - 27 + 4

The solutions to the quadratic equation are:

x = 27 + 4, x = - 27 + 4

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

x (x + 2) = e^{4}

(5 x - 1) (x + 1) = 0

x^{2} + 5 = 40

2 x^{2} - 7 + 3 = 0
