x^{2} - 1 = 3

x = 10, x = - 10

Decimal Notation

x = 3.16227 \dots, x = - 3.16227 \dots

Solution steps

x^{2} - 1 = 3

Square both sides:

x^{2} - 1 = 9

x^{2} - 1 = 9

Solve

x^{2} - 1 = 9 : x = 10, x = - 10

x = 10, x = - 10

Verify Solutions:

x = 10

True

, x = - 10

True

The solutions are

x = 10, x = - 10

x^{2} - 1 = 1

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
