Question 129592: If P(x)is a third degree polynomial and Q(x) is a fourth degree polynomial what can be said about the degree of P(x)+ Q(x). What I need here is an examples of polynomials that support this. thank you

Here goes the examples.

Let P(x) be a third degree polynomial as per the data given by you.

So P(x) =

and Q(x) be a fourth degree polynomial.

Q(x) =

So the addition of these would result in the following

Adding like terms we get:

P(x) + Q(x) =

thus the degree of the resulting polynomial would be equal to 4

Thus the solution
