5 (x - 9)^{2} = 720

x = 21, x = - 3

Solution steps

5 (x - 9)^{2} = 720

Divide both sides by

5

(x - 9)^{2} = 144

For

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

the solutions are

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

Solve

x - 9 = 144 : x = 21

Solve

x - 9 = - 144 : x = - 3

The solutions to the quadratic equation are:

x = 21, x = - 3

x^{2} - 9

7 x^{2} + 28 x - 35 = 0

- 5 m^{2} + 12 m + 8 = 3 - 5 m

x^{2} - 4 x = - 5 x

z (z - 3) = 5
