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

x = 33 - 3, x = - 33 - 3

Decimal Notation

x = 2.19615 \dots, x = - 8.19615 \dots

Solution steps

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

Move

81

to the right side

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

Divide both sides by

3

(x + 3)^{2} = 27

For

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

the solutions are

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

Solve

x + 3 = 27 : x = 33 - 3

Solve

x + 3 = - 27 : x = - 33 - 3

The solutions to the quadratic equation are:

x = 33 - 3, x = - 33 - 3

6 x - 64 = 2 x + 44

\frac{10}{x} > 6
