Question 330735
Assume the problem is:
{{{5x((4x^2 - x + 2) - ((7x^3 - 14x^2)/(7x^2)))}}}
The denominator will cancel so you have:
{{{5x((4x^2 - x + 2) - (x - 2))}}} 
Remove the interior brackets
{{{5x(4x^2 - x + 2 - x + 2))}}}
Combine like terms
{{{5x(4x^2 - 2x))}}}
distribute the 5x now
{{{20x^3 - 10x^2}}}
Factor out 10x^2
{{{10x^2(2x - 1)}}}
