x^{2} - 1 - 1 = 0

x = 2, x = - 2

Decimal Notation

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

Solution steps

x^{2} - 1 - 1 = 0

Move

1

to the right side

x^{2} - 1 = 1

Move

1

to the right side

x^{2} = 2

For

x^{2} = f (a)

the solutions are

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

x = 2, x = - 2

r, y = 2 (x + r)^{2} - s

2 x^{2} = 5 x + 5

2 x^{2} = 5 x + 7

2 x^{2} = 5 x + 1

3 x^{2} + 10 x = 8
