Question

verify whether values of (x) are roots of the equation or not.
( For question require the above picture) ​

Answer 1

$9 {x}^{2} - 3x - 2 = 0 \\ \\ if \: x = \frac{2}{3} \\ \\ 9 {( \frac{2}{3} )}^{2} - (3 \times \frac{2}{3} ) - 2 \\ \\ = 9 \times \frac{4}{9} - 2 - 2 \\ \\ = 4 - 4 \\ = 0$

$if \: x = - \frac{1}{3} \\ \\ 9 { (- \frac{1}{3}) }^{2} -( 3 \times - \frac{1}{3} ) - 2 \\ \\ = 9 \times (- \frac{1}{9} ) - ( - 1) - 2 \\ \\ = - 1 + 1 - 2 \\ = - 2$

2/3 is a root og this equation

-1/3 is not a root of this equation
