2 = x^{2} - 2

x = 2, x = - 2

Solution steps

2 = x^{2} - 2

Switch sides

x^{2} - 2 = 2

Move

2

to the right side

x^{2} = 4

For

x^{2} = f (a)

the solutions are

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

x = 4, x = - 4

4 = 2

- 4 = - 2

x = 2, x = - 2

x^{2} - 5 x - 31 = 5

x^{2} - 12 = - 3

x^{2} + 99 x - 37 = - 70

6 x^{2} - 11 x - 2 = 8

- 72 = - 10 b^{2} + 8
