What is true about the completely simplified sum of the polynomials 3x squared y squared minus 2 x y to the power of 5 and negat

12345 [234]

Answer:

The sum is a binomial with a degree of 6.

Step-by-step explanation:

To find : What is true about the completely simplified sum of the polynomials $3x^2y^2-2xy^5$ and $-3x^2y^2+3x^4y$ ?

Solution :

The polynomials $3x^2y^2-2xy^5$ and $-3x^2y^2+3x^4y$ ,

The sum of polynomial is given by,

$S=3x^2y^2-2xy^5+(-3x^2y^2+3x^4y)$

On simplifying , we get,

$S=3x^2y^2-2xy^5-3x^2y^2+3x^4y$

$S=-2xy^5+3x^4y$

Therefore, the result obtained is a binomial with a degree of 6.
