20 x^{2} + 3920 = 0

x = 14 i, x = - 14 i

Solution steps

20 x^{2} + 3920 = 0

Move

3920

to the right side

20 x^{2} = - 3920

Divide both sides by

20

x^{2} = - 196

For

x^{2} = f (a)

the solutions are

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

x = - 196, x = - - 196

- 196 = 14 i

- - 196 = - 14 i

x = 14 i, x = - 14 i

x^{2} - 10 x - 50 = 0

7 (x - 4)^{2} - 3 (x + 5) = 4 (x + 1) (x - 1) - 2

\frac{1}{2} x^{2} + x + \frac{1}{2} = 0

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

x^{2} - 3 a x + 2 a^{2} = 0
