Question 83587
Factor by grouping:
{{{3a^3+3ab^2+2a^2b+2b^3}}} Since there aren't any common factors, you can start factoring by grouping the terms as shown:
{{{(3a^3+3ab^2)+(2a^2b+2b^3)}}} Now you can factor common factors from each group:
{{{3a(a^2+b^2)+2b(a^2+b^2)}}} From here, you can factor the common factor of {{{(a^2+b^2)}}}
{{{(a^2+b^2)(3a+2b)}}}...and there you have it!
