120 = x^{2} - 1

x = 11, x = - 11

Solution steps

120 = x^{2} - 1

Switch sides

x^{2} - 1 = 120

Move

1

to the right side

x^{2} = 121

For

x^{2} = f (a)

the solutions are

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

x = 121, x = - 121

121 = 11

- 121 = - 11

x = 11, x = - 11

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

(5 - 2 x)^{2} - 16 = 0

3 b^{2} - 4 b + 1 = 0

x^{2} - 20 x + 40 = - 20

14 x + 15 x^{2} = 8
