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

WINSTONCH [101]

Given:

The polynomials are:

$3x^2y^2-2xy^5$

$-3x^2y^2+3x^2y^2+3x^4y$

To find:

The completely simplified sum of the polynomials.

Solution:

We have,

$3x^2y^2-2xy^5$

$-3x^2y^2+3x^2y^2+3x^4y$

The sum of given polynomials is:

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

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

Therefore, the sum of the given polynomials is $-2xy^5+3x^4y+3x^2y^2$ . It is a polynomial with degree 6 and leading coefficient -2.
