2 (x + 5)^{2} = 90

x = 35 - 5, x = - 35 - 5

Decimal Notation

x = 1.70820 \dots, x = - 11.70820 \dots

Solution steps

2 (x + 5)^{2} = 90

Divide both sides by

2

(x + 5)^{2} = 45

For

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

the solutions are

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

Solve

x + 5 = 45 : x = 35 - 5

Solve

x + 5 = - 45 : x = - 35 - 5

The solutions to the quadratic equation are:

x = 35 - 5, x = - 35 - 5

3 v^{2} = 7 v + 6

y^{2} - 7.8 y = - 12.65

x^{2} - 4 x - 10

C = (2 x - 3) (2 x - 2) - 2 x (x - 5)

25 x^{2} + 64 = 0
