3 x^{2} + 3 = 30

x = 3, x = - 3

Solution steps

3 x^{2} + 3 = 30

Move

3

to the right side

3 x^{2} = 27

Divide both sides by

3

x^{2} = 9

For

x^{2} = f (a)

the solutions are

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

x = 9, x = - 9

9 = 3

- 9 = - 3

x = 3, x = - 3

x, 2 x^{2} + 2 y^{2} + 2 x + 2 = 0

15 x^{2} + 24 x + 8 = 0

3 x^{2} + 9 x + 27

y, y^{2} = x^{3} (2 - x)

4 x^{2} - 9 x + 20 = 0
