x^{2} - 2 x - 63 = 0

x = 9, x = - 7

Solution steps

x^{2} - 2 x - 63 = 0

Move

63

to the right side

x^{2} - 2 x = 63

Rewrite in the form

(x + a)^{2} = b

(x - 1)^{2} = 64

For

the solutions are

f (x) = a, - a

Solve

x - 1 = 64 : x = 9

Solve

x - 1 = - 64 : x = - 7

The solutions to the quadratic equation are:

x = 9, x = - 7
