8 = \frac{x}{9} 9 x

x = 22, x = - 22

Decimal Notation

x = 2.82842 \dots, x = - 2.82842 \dots

Solution steps

8 = \frac{x}{9} \cdot 9 x

Switch sides

\frac{x}{9} \cdot 9 x = 8

Simplify

x^{2} = 8

For

x^{2} = f (a)

the solutions are

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

x = 8, x = - 8

8 = 22

- 8 = - 22

x = 22, x = - 22

2 x^{2} + 16 x + 7 = 0

6 x (x - 1) = 28 - 19 x

0 = 2 x^{2} - 18

3 - x^{2} + 2 x

0 = x (x - 4)
