x^{2} - 1 = 1

x = 2, x = - 2

Decimal Notation

x = 1.41421 \dots, x = - 1.41421 \dots

Solution steps

x^{2} - 1 = 1

Square both sides:

x^{2} - 1 = 1

x^{2} - 1 = 1

Solve

x^{2} - 1 = 1 : x = 2, x = - 2

x = 2, x = - 2

Verify Solutions:

x = 2

True

, x = - 2

True

The solutions are

x = 2, x = - 2

x^{2} - 6 x - x^{2} - 6 x - 3 = 5

- 1 - 10 k = - 2 - 2 k + 3

x - 8 x + 15 = 0

x + x^{2} - 4 \cdot x + 4 = 0

x + 1 = 9
