(3 x + 6)^{2} = 81

x = 1, x = - 5

Solution steps

(3 x + 6)^{2} = 81

For

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

the solutions are

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

Solve

3 x + 6 = 81 : x = 1

Solve

3 x + 6 = - 81 : x = - 5

The solutions to the quadratic equation are:

x = 1, x = - 5

4 x^{2} + 9 x - 11 = 2 x^{2} + 10 x

x^{2} + (2 x)^{2} = 80

- 4.9 x^{2} + 5 x + 40 = 0

x^{2} + 2 x = - 26

a^{2} = 2 a - 1
