Question 55100
Factor:
{{{(3mp-12mr)-(4nr-np)}}} From the first set of parentheses, you can factor 3m and from the second set of parentheses you can factor n to give you:
{{{3m(p-4r)-n(4r-p)}}} You can change the second term from{{{-n(4r-p)}}}to +{{{+n(p-4r)}}} to give you:
{{{3m(p-4r)+n(p-4r)}}} Now you can factor the {{{(p-4r)}}} to get:
{{{(p-4r)(3m+n)}}}...and you're done!
