2 (x + 3)^{2} = 90

x = 35 - 3, x = - 35 - 3

Decimal Notation

x = 3.70820 \dots, x = - 9.70820 \dots

Solution steps

2 (x + 3)^{2} = 90

Divide both sides by

2

(x + 3)^{2} = 45

For

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

the solutions are

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

Solve

x + 3 = 45 : x = 35 - 3

Solve

x + 3 = - 45 : x = - 35 - 3

The solutions to the quadratic equation are:

x = 35 - 3, x = - 35 - 3

t + t^{2} = 0

\frac{x ^{2}}{3} = 3 x

4 x (x + 7) + 48 = 0

- 12 w = 4 w^{2} + 9

(f - 2)^{2} = - 4 f^{2}
