3 x^{2} - 1 = 11

x = 2, x = - 2

Solution steps

3 x^{2} - 1 = 11

Move

1

to the right side

3 x^{2} = 12

Divide both sides by

3

x^{2} = 4

For

x^{2} = f (a)

the solutions are

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

x = 4, x = - 4

4 = 2

- 4 = - 2

x = 2, x = - 2

y^{2} + 9 y - 10 = 0

250 = 2 x^{2} + \frac{x ^{2}}{2}

x, 3 x^{2} + x^{2} y = C

3 = (x - 1)^{2} + 3 (x + 2)

(7 + 2 x) (3 + 2 x) = 56
