15 = x^{2} - 1

x = 4, x = - 4

Solution steps

15 = x^{2} - 1

Switch sides

x^{2} - 1 = 15

Move

1

to the right side

x^{2} = 16

For

x^{2} = f (a)

the solutions are

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

x = 16, x = - 16

16 = 4

- 16 = - 4

x = 4, x = - 4

x^{2} = x - 3

2 x^{2} - 1 = 4

x^{2} - 20 = 22 - x

x, k x^{2} - 12 x + 4 = 0

(3 - x) (x + 1) = 0
