5 x^{2} + 5 = - 15

x = 2 i, x = - 2 i

Solution steps

5 x^{2} + 5 = - 15

Move

5

to the right side

5 x^{2} = - 20

Divide both sides by

5

x^{2} = - 4

For

x^{2} = f (a)

the solutions are

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

x = - 4, x = - - 4

- 4 = 2 i

- - 4 = - 2 i

x = 2 i, x = - 2 i

2 x^{2} - 6 = 3 x

5 x^{2} + x = - 5

7 x + 120 = x^{2}

2 a^{2} + 11 a - 21 = 0

3 x^{2} - \frac{1}{75} = 0
