x^{2} - 4 x - 5 = 0

x = 5, x = - 1

Solution steps

x^{2} - 4 x - 5 = 0

Move

5

to the right side

x^{2} - 4 x = 5

Rewrite in the form

(x + a)^{2} = b

(x - 2)^{2} = 9

For

the solutions are

f (x) = a, - a

Solve

x - 2 = 9 : x = 5

Solve

x - 2 = - 9 : x = - 1

The solutions to the quadratic equation are:

x = 5, x = - 1

x^{2} + 26 x

- 10 x^{2} + x + 11 = 0

8 x^{2} + 32 x = 0

8^{2} + b^{2} = 1 0^{2}

14 x^{2} - 33 x - 5 = 0
