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