(x + 3)^{2} - 81 = 0

x = 6, x = - 12

Solution steps

(x + 3)^{2} - 81 = 0

Move

81

to the right side

(x + 3)^{2} = 81

For

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

the solutions are

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

Solve

x + 3 = 81 : x = 6

Solve

x + 3 = - 81 : x = - 12

The solutions to the quadratic equation are:

x = 6, x = - 12

x^{2} + 2 x + 2 + 8 = 0

x^{2} + 11 x - 80 = 0

- x^{2} - 14 = 8 x + 2

w^{2} + w + 1 = 0

x, x^{2} + y^{2} = c x
