(x - 20)^{2} = 81

x = 29, x = 11

Solution steps

(x - 20)^{2} = 81

For

(g (x))^{2} = f (a)

the solutions are

g (x) = f (a), - f (a)

Solve

x - 20 = 81 : x = 29

Solve

x - 20 = - 81 : x = 11

The solutions to the quadratic equation are:

x = 29, x = 11

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

z^{2} = 38

5 u^{2} - 9 u - 2 = 0

(x - m) (x - n) = k^{2}

x^{2} + 1 = 6 x
