Question 3836
the second and third terms are the same (they are both {{{x^2y^2}}} terms), so we can add them to give {{{x^2 + 3x^2y^2}}}. Leave it like that...you cannot add anything else.


However, what mathematicians prefer to do, is to factorise something...ie write it as "one thing" multiplied by "another thing". So, we get, {{{x^2(1+3y^2)}}}


I would leave it in this form.
