Well, it is 3 polynomials so let’s break it down first.

(-3x*2 -2xy +y*2) (-4x*2 -xy + 6y*2)

Let’s add these first. The rule is to drop parentheses and add regularly. Bases stay the same, powers add and coefficients multiply.

Ans: (-7x*4 -3x*2 y*2 + 7y*4)

Now let’s add it with the last one.

The answer is: -6x*6 +3x*3 y*3 -6y*6

The polynomial obtained after adding the following polynomial is 3x +3xy +4y²-3x².

What are Polynomials ?

A polynomial  can be defined as  a mathematical expressions made up of indeterminate and coefficients and involving only addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

It is given in the question to add the polynomials

- 3x - 2xy + y²

- 4x² - xy +6y²

x²+ 6xy- y²

Adding the coefficients of like variables having same coefficients.

3x - 2xy + y² + (- 4x² - xy +6y²) + ( x²+ 6xy- y² )

3x -2xy+y² -4x² - xy +6y² + x²+ 6xy- y²

3x +3xy +4y²-3x²

The polynomial obtained after adding the following polynomial is 3x +3xy +4y²-3x².
