3 (x + 2)^{2} - 15 = 0

x = 5 - 2, x = - 5 - 2

Decimal Notation

x = 0.23606 \dots, x = - 4.23606 \dots

Solution steps

3 (x + 2)^{2} - 15 = 0

Move

15

to the right side

3 (x + 2)^{2} = 15

Divide both sides by

3

(x + 2)^{2} = 5

For

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

the solutions are

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

Solve

x + 2 = 5 : x = 5 - 2

Solve

x + 2 = - 5 : x = - 5 - 2

The solutions to the quadratic equation are:

x = 5 - 2, x = - 5 - 2

9 x^{2} - 9 x = 0

x (x - 2) = x + 4

7000 - 2 Q = 0.1 Q^{2} + 2 Q + 1000

12 x - 0.24 x^{2} = 0

x^{2} + 8 x - 20
