Question

If x ²- 1/9=0 then find the value of x

Answer 1

Answer:

$x = \frac{1}{3} \: \: \: \: or \: \: \: \: \: x = \frac{ - 1}{3} .$

Step-by-step explanation:

${x}^{2} - \frac{1}{9} = 0 \\ \\ (x - \frac{1}{3} )(x + \frac{1}{3} ) = 0 \\ \\ x = \frac{1}{3} \: \: \: \: \: or \: \: \: \: \: x = \frac{ - 1}{3} .$
