2 x^{2} + 30 = 0

x = 15 i, x = - 15 i

Solution steps

2 x^{2} + 30 = 0

Move

30

to the right side

2 x^{2} = - 30

Divide both sides by

2

x^{2} = - 15

For

x^{2} = f (a)

the solutions are

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

x = - 15, x = - - 15

- 15 = 15 i

- - 15 = - 15 i

x = 15 i, x = - 15 i

16 (4 x - 1)^{2} = 25

x^{2} - 18 x + 82

x, x^{2} y^{2} + 2 x - 6 = 0

6 x^{2} - x + 6 = 0

3 x^{2} - 48 x + 180 = 0
