x^{2} - 8 = - 1

x = 7, x = - 7

Decimal Notation

x = 2.64575 \dots, x = - 2.64575 \dots

Solution steps

x^{2} - 8 = - 1

Move

8

to the right side

x^{2} = 7

For

x^{2} = f (a)

the solutions are

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

x = 7, x = - 7

- 13 x + 12 = 13 x - 13

\frac{3}{4 ^{3}}

2 g + 1 \geq 9

3 x + 2 = 2 x + 7

x^{2} - 3 x + \frac{9}{4} = 0
