x^{2} - 8 x - 17 = 0

x = 33 + 4, x = - 33 + 4

Decimal Notation

x = 9.74456 \dots, x = - 1.74456 \dots

Solution steps

x^{2} - 8 x - 17 = 0

Move

17

to the right side

x^{2} - 8 x = 17

Rewrite in the form

(x + a)^{2} = b

(x - 4)^{2} = 33

For

the solutions are

f (x) = a, - a

Solve

x - 4 = 33 : x = 33 + 4

Solve

x - 4 = - 33 : x = - 33 + 4

The solutions to the quadratic equation are:

x = 33 + 4, x = - 33 + 4

5 x^{2} - 10 x - 12 = 0

1 2^{2} + x^{2} = 1 4^{2}

- 4 x^{2} = 48

5 x^{2} - 2 x - 3 = 0

c (x) = 2 x^{2} - 18 x + 680
