Is the sum of two polynomials of degree n always a polynomial of degree n? Why or why not?

Supposing the coefficients of the degree n terms are negatives of one another.  Then the sum of the nth degree terms is zero, and the resulting polynomal is not of degree n.

If you are working with less than, or greater than. If there is a negative do you switch the sign? For example 9t-4>32
kirill [66]

Answer:

Rule:  If working with an inequality and you either mult. or div. by a negative number, you must reverse the direction of the inequality symbol.

Step-by-step explanation:

Your job here is to simplify 9t-4>32, in which the variable (t) is already positive.  Here you do NOT switch signs or reverse the direction of the inequality symbol.  Adding 4 to both sides, we get 9t > 36, or t > 4.

If, however, you had  -9t-4>32 to work with, the situation would be different because t in this inequality is negative.  Adding 4 to both sides results in:

-9t > 36.  To solve for t, we must divide both sides by -9 AND reverse the direction of the inequality symbol:

t < -4.

Rule:  If working with an inequality and you either mult. or div. by a negative number, you must reverse the direction of the inequality symbol.
