2 x^{2} - 392 = 0

x = 14, x = - 14

Solution steps

2 x^{2} - 392 = 0

Move

392

to the right side

2 x^{2} = 392

Divide both sides by

2

x^{2} = 196

For

x^{2} = f (a)

the solutions are

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

x = 196, x = - 196

196 = 14

- 196 = - 14

x = 14, x = - 14

(3 x + 1)^{2} = 27

x, x^{2} - y^{2} + z = 0

x^{2} + 3 x = 7 x

4 x - 15 + 5 x + 3 = x^{2} + 2 x

5 x^{2} - 15 x + 3
