A polynomial is a mathematical expression involving sums of variable terms with exponents multiplied by coefficients. Polynomials can include constants, variables with positive whole number exponents, and sums of these terms, but cannot include divisions of variables. The document provides examples of adding, subtracting, multiplying, and dividing polynomials and explains the methods for working through each type of problem, such as collecting like terms or multiplying terms within brackets. Resources for further learning about polynomials are also included.

1. Polynomial
Summary:
A polynomial is a mathematical expression involving a sum of powers in one or more
variables multiplied by coefficients.
Polynomial can have:
 A constant (any number)
 Variables (unknown values like x and y)
 Exponents(the 2 in y^2 is an exponents. Basically it’s the power. Exponentsmust
be a positive whole number like 1, 2, 3… )
 A polynomial can have constants, variables and exponents,
but never division by a variable
Example/Questions:
Adding polynomial
(Q1) ADD
Subtracting Polynomial
(Q2) Subtract
Multiplying polynomial
(Q3) Multiplyout
Dividing Polynomials
(Q4) Divide
Answer:

2. (Q1)
(Q2)
(Q3)
(Q4)
Method towards answer:
(Q1)
 Place like terms together AND add the like terms
 Answer you should be left with will be ==
(Q2)
 First expand the bracket by multiplying the minus sign on the quadratic equation
 Collect the like terms together
 Subtract
 Answer should be
(Q3)
 Multiply the 2x with x and 3xy.
When you have done this you should be left with 2(x^2)+6(x^2)(y)
(Q4)
 Separate all of your teams into single fractions

3.  You can simplifythe first two fraction with 3x (since 3x is the highest value that
can be cancelled out). 1/3x remains the same since this already Simplified
 At the end you will be left with 3x+4+1/3x
Problems faced while trying to grasp subject area:
For thistopic there was not a lot of problems that I found. Finding resources and
examples were simple and was explained very well.
