The sum is a trinomial with a degree of 6.
The sum is a binomial with a degree of 5.
The sum is a binomial with a degree of 6.

Answer 1

help any one

Answer 2

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

Answer 3

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

Answer 4

so a b c or d

Answer 5

now lets see on our binominal

(Binominal is polynomial with two terms)

the degree of our binomial is 6, since 5+1=6.

Answer 6

d
