x^{2} - 8 x = 9

x = 9, x = - 1

Solution steps

x^{2} - 8 x = 9

Rewrite in the form

(x + a)^{2} = b

(x - 4)^{2} = 25

For

the solutions are

f (x) = a, - a

Solve

x - 4 = 25 : x = 9

Solve

x - 4 = - 25 : x = - 1

The solutions to the quadratic equation are:

x = 9, x = - 1

x, 2 7^{x} = 3

x, \frac{1}{2} x < - 3

- 6 x^{2} - 11 x - 4
