$7{x}^{2}-24x+9=0$

Expert

$7{\left(X\right)}^{2}-24X+9=0$
$\left(7X-3\right)\left(X-3\right)=0$
either
7 X - 3 = 0 --------- add 3 to both sides
7 X = 3 ------------- divide both sides over 7
$X=\frac{3}{7}$
or
X - 3 = 0 --------- add 3 to both sides.
X = 3
answer --------- $X=\frac{3}{7}$ , or X = 3.
