2 x^{2} - 6 = - 168

x = 9 i, x = - 9 i

Solution steps

2 x^{2} - 6 = - 168

Move

6

to the right side

2 x^{2} = - 162

Divide both sides by

2

x^{2} = - 81

For

x^{2} = f (a)

the solutions are

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

x = - 81, x = - - 81

- 81 = 9 i

- - 81 = - 9 i

x = 9 i, x = - 9 i

y, \frac{x ^{2}}{9} + \frac{y ^{2}}{16} = 1

x (x - 15) + 54 = 0

x, x^{2} + y^{2} + 2 z^{2} = 1

- \frac{1}{3} q^{2} - 10 q + 112 = \frac{1}{4} q^{2} + 5 q + 1

7 x^{2} - 8 x - 6 = 0
