Simplifying the equation, it should be
![-z^{2}](https://tex.z-dn.net/?f=%20-z%5E%7B2%7D%20)
-2z-2.
Answer:
2nd first third first 1st last
Step-by-step explanation:
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 ![29x^2 - 7?](https://tex.z-dn.net/?f=%2029x%5E2%20-%207%3F)
You must take off first and second terms at all and add termw with
and coefficient. Thus, you have to subtract polynomial
.
Check:
![21x^4 + 3y - 6x^2 + 34-(21x^4+3y-35x^2+41)=21x^4+3y-6x^2+34-21x^4-3y+35x^2-41=x^2(-6+35)+(34-41)=29x^2-7.](https://tex.z-dn.net/?f=21x%5E4%20%2B%203y%20-%206x%5E2%20%2B%2034-%2821x%5E4%2B3y-35x%5E2%2B41%29%3D21x%5E4%2B3y-6x%5E2%2B34-21x%5E4-3y%2B35x%5E2-41%3Dx%5E2%28-6%2B35%29%2B%2834-41%29%3D29x%5E2-7.)
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 ![-21x^4+6x^2.](https://tex.z-dn.net/?f=-21x%5E4%2B6x%5E2.)
Check:
![21x^4 + 3y - 6x^2 + 34+(-21x^4+6x^2)=21x^4 + 3y - 6x^2 + 34-21x^4+6x^2=3y+34.](https://tex.z-dn.net/?f=21x%5E4%20%2B%203y%20-%206x%5E2%20%2B%2034%2B%28-21x%5E4%2B6x%5E2%29%3D21x%5E4%20%2B%203y%20-%206x%5E2%20%2B%2034-21x%5E4%2B6x%5E2%3D3y%2B34.)
Answer: 1)
2) ![-21x^4+6x^2.](https://tex.z-dn.net/?f=-21x%5E4%2B6x%5E2.)
