2 (x + 4)^{2} = 90

x = 35 - 4, x = - 35 - 4

Decimal Notation

x = 2.70820 \dots, x = - 10.70820 \dots

Solution steps

2 (x + 4)^{2} = 90

Divide both sides by

2

(x + 4)^{2} = 45

For

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

the solutions are

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

Solve

x + 4 = 45 : x = 35 - 4

Solve

x + 4 = - 45 : x = - 35 - 4

The solutions to the quadratic equation are:

x = 35 - 4, x = - 35 - 4

\frac{3}{2 ^{3}}

- 6.3 = - (x - 10) + 0.4

x + 2 x + 1 = 3 x + 2 + 3

- 5 x + 8 \leq - 4 x + 2

(1 + \frac{0.05}{4})^{4}
