Division of Polynomials
Division of polynomials is sometimes referred to as algebraic long division.
So lets say we have
2x+4 and we want to divide it by 2
2x+4/2
You are not really going to change the value. You are only going

Opposites of Polynomials
Whenever polynomials are being subtracted, the opposite will be added, just as with real numbers.
How do you find the opposite of a polynomial?
Remember that the opposite of 5 is -5 and the opposite of
MTH 209 Week 1 Discussion 1
Addition and Subtraction of Polynomials
In order to add a polynomial you have to add together any like terms. A like term is a term whose
variable and their exponent are the same. So simply put like terms are terms that are lik

Monomials vs. polynomials
A monomials is a variable, number, or a product of a variable and a number where all of the exponents
are whole numbers.
The degree of a monomial is the sum that you get when you add the exponents of a
1) Work:
a. For x = 75
z = (75-90)/22 = -15/22
b. For x = 100 z = (100-90)/22 = 10/22 = 5/11
Answer: z-values are -15/22 and 5/11, the first sore is negative because 75<90 and the
second one positive because 100>90
2) Work:
a) P(400<X<415)=P(0<Z<15/10) =
I want to review our topics this week also included the polynomials and
addition ,subtraction, division multiplication and simplifying.
A polynomial is a sentence which has no true answers but is made up of
many terms.
Poly stands for many and nominal rep
