x^{2} - 8 x = 20

x = 10, x = - 2

Solution steps

x^{2} - 8 x = 20

Rewrite in the form

(x + a)^{2} = b

(x - 4)^{2} = 36

For

the solutions are

f (x) = a, - a

Solve

x - 4 = 36 : x = 10

Solve

x - 4 = - 36 : x = - 2

The solutions to the quadratic equation are:

x = 10, x = - 2

x, - \frac{2}{5} x = \frac{1}{5}

\frac{π}{9}

x, x - \frac{2}{3} = \frac{4}{5}

56 (5)

5 x^{2} (2 x - 3)
