2 - 2 x^{2} = - 30

x = 4, x = - 4

Solution steps

2 - 2 x^{2} = - 30

Move

2

to the right side

- 2 x^{2} = - 32

Divide both sides by

- 2

x^{2} = 16

For

x^{2} = f (a)

the solutions are

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

x = 16, x = - 16

16 = 4

- 16 = - 4

x = 4, x = - 4

x^{2} + 14 x + c

4 (x^{2} - 8) + 3 = - 5

3 x^{2} + 51 = 24 x

3 x^{2} - 18 x - 15 = 0

x^{2} + 30 x = 231
