(2 x + 4)^{2} = 100

x = 3, x = - 7

Solution steps

(2 x + 4)^{2} = 100

For

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

the solutions are

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

Solve

2 x + 4 = 100 : x = 3

Solve

2 x + 4 = - 100 : x = - 7

The solutions to the quadratic equation are:

x = 3, x = - 7

x^{2} + 8 x + 16 = 64

5 (x - 7)^{2} + 27 = 32

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

2 x^{2} - 4 x + 10 = 0

2 x^{2} - x + 55 = (x + 5)^{2}
