- 15 x^{2} + 15 = 0

x = 1, x = - 1

Solution steps

- 15 x^{2} + 15 = 0

Move

15

to the right side

- 15 x^{2} = - 15

Divide both sides by

- 15

x^{2} = 1

For

x^{2} = f (a)

the solutions are

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

x = 1, x = - 1

1 = 1

- 1 = - 1

x = 1, x = - 1

2 x^{2} + 0.2 x - 0.12 = 0

6 x^{2} + 2 x + 8 = 0

24 = 4 + 37 x - 16 x^{2}

3 x^{2} + x = 10

x^{2} + 16 x = - 62
