Consider the polynomial This polynomial has four terms:
- term of 4th degree;
- term of 1st degree;
- term of 2nd degree;
- term of 0 degree or simply the coefficient without variables.
1. What polynomial must be subtracted from it to obtain
You must take off first and second terms at all and add termw with and coefficient. Thus, you have to subtract polynomial .

2. What polynomial must be added to it to obtain a first degree polynomial?
If you want to obtain a 1st degree polynomial, then you must take off terms of 4th and 2nd degree. So you have to add

Answer: 1) 2)
12*3=36 pounds. so therefore 36
So to start you should get x and y on the same side and get the numbers on one side. Then you should cancel out a variable. Because both y’s are 1 and they are opposite charges they will both cancel out to 0. Then add what is remaining which is the 2x and the 3x and equal that to +9-4 which equals 5. You want x to be all by itself so you would divide both sides by 5 and get that x=1. Then you would just substitue and solve for y. Hope this helped!
