Answer:
- 5yz^2 - 3z^2 - 5y + 7
Step-by-step explanation:
The polynomial is:
[tex]-yz^2-3z^2-4y+4[/tex] ( 1 )
this polynomial is the result of the sum of two polynomials, one of them given by
[tex]y-4yz^2-3[/tex] ( 2 )
if you find to know what is the other polynomial, you can take the difference between the polynomial (1) and (2). It is necessary to take the difference between simmilar terms, as follow:
- yz^2 - 3z^2 - 4y + 4
- (4yz^2 + y - 3 )
- yz^2 - 3z^2 - 4y + 4
- 4yz^2 - y + 3
- 5yz^2 - 3z^2 - 5y + 7
hence the other polynomial is - 5yz^2 - 3z^2 - 5y + 7
