Divide using synthetic division, and write a summary statement in fraction form. 2x^4-x^3-15x^2+3x/x+3
aev [14]
So... first off, we sort the dividend, the numerator, in descending order... so, looking at the exponents in this one, is already sorted in descending order, from 4 down to 1, so that's done.

then the divisor, we have x+3, that means x + 3 = 0, x = -3,
so, we'll be using -3 for the synthetic division then.

\bf \cfrac{2x^4-x^3-15x^2+3x}{x+3}\\\\
-------------------------------\\\\

\begin{array}{r|rrrrrrrrrl}
-3&&2&-1&-15&3\\
&&&-6&21&-18\\
--&&-&--&--&--\\
&&2&-7&6&\boxed{-15}&\leftarrow remainder
\end{array}

and now, we'll use those coefficients, dropping the exponents of the polynomial by one, and the remainder, remains as a fraction with the divisior of x+3.

\bf 2x^3-7x^2+6x-\frac{15}{x+3}

The degree of a vertex is <br><br> Help please
Nina [5.8K]

Answer:

is the number of graph edges which touch v

Step-by-step explanation:

To find the degree of a graph, figure out all of the vertex degrees.  The degree of the graph will be its largest vertex degree.   The degree of the network is 5.  

 

Once you know the degree of the verticies we can tell if the graph is a traversable by lookin at odd and even vertecies.  First lets look how you tell if a vertex is even or odd.
