Very useful for those struggling with these concepts and there are many out there including parents struggling to help their kids in grades 6 to 8 with basic algebra. A very nice treatment of this topic and I think you should also create a YouTube channel and make short videos to go with each of your hubs and before long you will have lots of mathematics students following you.
Great work. I have to confess, I got confused and frustrated after the first paragraph. Math and I don't get on. But from what I could comprehend this seems to be a good hub and I don't doubt you'll be helping loads of people who maybe didn't understand their instructor's explanation.

The meaning of polynomial is associated expression that has several terms. It is defined a single term or a sum of the finite number of term. Each term consists of the product of a constant called the coefficient of the term and a finite number of variables usually represented by letters raised to integer powers. Note: If an expression has a variable under the square root sign or in the denominator, then 7 the expression is not a polynomial.
Remarks: First-degree polynomials are called linear polynomials Second-degree polynomials are called quadratic polynomials Third-degree polynomials are called cubic polynomials Fourth-degree polynomials are called quartic polynomials Fifth-degree polynomials are called quantic polynomials. Similar terms — are terms with the same literal coefficients means same letters with the same exponents.
To add like terms, add their numerical coefficients, and prefix this sum as the numerical factor of the literal part. The process consists of adding the negative of the subtrahend to the minuend and then applying the rule for addition of polynomials. To remove parenthesis the general term for any grouping symbols preceded by a positive sign, simply drop the parenthesis without changing the signs of the terms inside. To remove parenthesis preceded by a negative sign, change the signs of the terms inside the grouping symbols to their opposite.

Practice Questions on Polynomial Expressions. FAQs on Polynomial Expressions. What Is a Polynomial Expression? We need to check the following points to know if an expression is a polynomial: 1. What Are the 3 Types of Polynomials? The difference between a polynomial and an equation is explained as follows: A polynomial is an expression that consists of coefficients, variables, constants, operators, and non-negative integers as exponents. What Is a Zero Polynomial?
What Is an Example of a Zero Polynomial? The example of a zero polynomial is 3 because its degree is zero.
What Are the Terms in a Polynomial? How Do you Solve Polynomial Expressions? The polynomial expressions are solved by: Combining like terms monomials having the same variables using arithmetic operations. So in this case we have,. This part is here to remind us that we need to be careful with coefficients. These are very common mistakes that students often make when they first start learning how to multiply polynomials.

Example 1 Perform the indicated operation for each of the following. Show Solution The first thing that we should do is actually write down the operation that we are being asked to do. Here is the work for this problem.
Example 2 Multiply each of the following. Again, we will just FOIL this one out. That is all that we need to do here. Example 3 Multiply each of the following. This one is nearly identical to the previous part.
