Question 199786
I'm assuming you want to factor {{{2x^2-14x+3x-21}}}



{{{2x^2-14x+3x-21}}} Start with the given expression



{{{(2x^2-14x)+(3x-21)}}} Group like terms



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



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



So {{{2x^2-14x+3x-21}}} factors to {{{(2x+3)(x-7)}}}
