a = (2 x + 6) \cdot (2 x + 6)

x = \frac{a - 6}{2}, x = \frac{- a - 6}{2}

Solution steps

a = (2 x + 6) (2 x + 6)

Switch sides

(2 x + 6) (2 x + 6) = a

Simplify

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

For

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

the solutions are

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

Solve

2 x + 6 = a : x = \frac{a - 6}{2}

Solve

2 x + 6 = - a : x = \frac{- a - 6}{2}

The solutions to the quadratic equation are:

x = \frac{a - 6}{2}, x = \frac{- a - 6}{2}

\frac{1}{2} x^{2} + 2 x + 1 = 0

2 x^{2} + 5 = 3

10 x^{2} - 256 = 300

9 x^{2} = 18

(k - (- 1)) (k + 1) = - 13 (- 1) - 2 k
