Q:
# Add the following polynomials, t- 3x2 - 2xy + y2- 4x2 - xy +6y2x2+ 6xy- y2

Accepted Solution

A:

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
