7 x^{2} - 105 = 0

x = 15, x = - 15

Solution steps

7 x^{2} - 105 = 0

Move

105

to the right side

7 x^{2} = 105

Divide both sides by

7

x^{2} = 15

For

x^{2} = f (a)

the solutions are

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

x = 15, x = - 15

2 (3 x^{2} - 1) = - x

- 2 n^{2} = 14

2 x^{2} - 3 = 19

x^{2} - 16 x + 12 = 0

x^{2} + 3 x - 10 = 0
