Question 132288


{{{7x^3-28x^2-3x+12}}} Start with the given expression


{{{(7x^3-28x^2)+(-3x+12)}}} Group like terms



{{{7x^2(x-4)-3(x-4)}}} Factor out the GCF {{{7x^2}}} out of the first group. Factor out the GCF {{{-3}}} out of the second group



{{{(7x^2-3)(x-4)}}} Since we have the common term {{{x-4}}}, we can combine like terms


So {{{7x^3-28x^2-3x+12}}} factors to {{{(7x^2-3)(x-4)}}}
