2 (x + 6)^{2} = 18

x = - 3, x = - 9

Solution steps

2 (x + 6)^{2} = 18

Divide both sides by

2

(x + 6)^{2} = 9

For

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

the solutions are

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

Solve

x + 6 = 9 : x = - 3

Solve

x + 6 = - 9 : x = - 9

The solutions to the quadratic equation are:

x = - 3, x = - 9

y, y^{3} = x^{2}

x^{2} - 9 x + 1 = 1

10 x^{2} = 3 x

x^{2} - x + 5 = 5

y, x^{2} + y^{2} = - 1
