- 8 x^{2} = 392

x = 7 i, x = - 7 i

Solution steps

- 8 x^{2} = 392

Divide both sides by

- 8

x^{2} = - 49

For

x^{2} = f (a)

the solutions are

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

x = - 49, x = - - 49

- 49 = 7 i

- - 49 = - 7 i

x = 7 i, x = - 7 i

\frac{1}{2} 9.8 (x - 40)^{2} = 0

12 x^{2} - 200 x + 630 = 0

225 = x^{2} + 7 x

0 = 3 X^{2} - 4 X + 5

x, x^{2} - 2 x - 4 = 0
