- 3 x^{2} + 15 = 0

x = 5, x = - 5

Decimal Notation

x = 2.23606 \dots, x = - 2.23606 \dots

Solution steps

- 3 x^{2} + 15 = 0

Move

15

to the right side

- 3 x^{2} = - 15

Divide both sides by

- 3

x^{2} = 5

For

x^{2} = f (a)

the solutions are

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

x = 5, x = - 5

15 q^{2} + 31 q + 15 = 5

(2 x + 1) (x + 1) + (2 x - 1) x = 7

n (4 + 2 n) - 4 (n - 6) = 74

3 x^{2} - 22 x + 7 = 0

x, 4 x^{2} + 22 x = 12
