Notice that if you removed a common factor of+2in the first step, the two sets of parentheses would not contain the same expression. If the expressions inside the two sets of parentheses are not exactly the same, you cannot express the polynomial as a product of two factors! Factoring Trin...
The difference of two squares, or just the difference of squares, is a special case of polynomials. A polynomial in one variable, x, is defined as either a single term or a sum of terms of the form axn. For each term, a is the coefficient of the term and n is the degree of the...
Factoring Polynomial Expressions Apolynomialis an expression with two or more (poly) terms (nomial). Polynomials often need to be factored in order to be solved. In this case, factoring means to organize or simplify. Many people are comfortable multiplying terms together and even using theF.O....

Quadratic polynomial is a polynomial where the highest degree of a term is in degree two. When factoring quadratic polynomials, we are simply doing the FOIL method in reverse. Here are some things that will help you factor quadratic polynomials. ...

The factoring method in the last two examples above — in particular, the part where I picked two numbers for splitting the middle term of the quadratic — probably look fairly magical to you right now. That's okay. For a complete explanation of these last two examples, please study my le...
Recall: Factoring expressions is one of thegateway skillsthat is necessary for much of what we do in algebra for the rest of the course. The wordfactorhas two meanings and both are important. Exercise #1: Consider the expression. (a) Identify the GCF of the expression. (b) Factor the gi...
A perfect square trinomial is a trinomial that can be written as the square of a binomial. Recall that when a binomial is squared, the result is the square of the first term added to twice the product of the two terms and the square of the last term....
To eliminate common factors out of a polynomial, you have to divide each term by the GCF. For example, to factor 6 x 2 + 9 x, you have to divide both terms by the GCF. That will give you the result 3 x ( 2 x + 3 )
