Simplify the expression
5x36x28x2x210x+12\displaystyle {\frac{{{5}{x}^{{3}}-{6}{x}^{{2}}-{8}{x}}}{{{2}{x}^{{2}}-{10}{x}+{12}}}}
and give your answer in the form of
f(x)g(x).\displaystyle {\frac{{{f{{\left({x}\right)}}}}}{{{g{{\left({x}\right)}}}}}}.

Your answer for the function f(x)\displaystyle {f{{\left({x}\right)}}} is :  
Your answer for the function g(x)\displaystyle {g{{\left({x}\right)}}} is :
