    there is your sum \[3x^2y^2 − 2xy^5+(−3x^2y^2 + 3x^4y)\] release the brackets \[3x^2y^2 − 2xy^5-3x^2y^2 + 3x^4y)\] combine like terms now

    terms 3x2y2 and -3x2y2 make up 0. So there are left \[3x^4y-2xy^5\]

    now lets see on our binominal (Binominal is polynomial with two terms) the degree of our binomial is 6, since 5+1=6.
