Answer:

Step-by-step explanation:
Any polynomial will have degrees of variable in integers and the degrees would be always positive.
It is conventional to write standard forms of polynomials in the descending powers of x.
i.e. we write for cubic polynomial the term containing x cube, and for power 5 polynomial, the term containing power 4, next power 3, thus strictly in descending order.
The given polynomial is

This is a polynomial because all x have powers in positive integers.
But this is not in standard form as highest degree of 4 is not the first term
Let us rearrange according to powers of m
We get

as standard form
So first you do 5/5 = 1 then you multiply 2*7 = 14 then you do 1 - 14 = - 13
Hope this helps!
Answer:
1/2
Step-by-step explanation:
The problem is asking for the coefficient of the sum of the two expressions, which are 2/3 and -1/6.
2/3 + -1/6 = 1/2, therefore, the answer is 1/2.
