z^{2} - 1 = 0

z = 1, z = - 1

Solution steps

z^{2} - 1 = 0

Move

1

to the right side

z^{2} = 1

For

x^{2} = f (a)

the solutions are

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

z = 1, z = - 1

1 = 1

- 1 = - 1

z = 1, z = - 1

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

4 (3 x - 8)^{2} - 17 = 19

4 x^{2} + 11 x = 3

5 (x + 3) - 5 (x^{2} - 1) = x^{2} + 7 (3 - x) - 1

8 x^{2} - 128 = 0
