Factoring Trinomials with a Common Factor

Two lessons for the price of one! Learners use algebra tiles to multiply binomials in the first lesson, Next, they use their knowledge from the first lesson to factor trinomials into two binomials.

Work your way through factoring polynomials with a learning exercise that starts with the GCF and ends with factoring by grouping. Each page provides an example as well as an answer key for each section. 

Teach how to factor trinomials using quadratic methods with this tutorial video. Each example begins by factoring a greatest common factor, resulting in a quadratic factor. The instructor then shows how to factor the quadratic factor.

Introduce your class to the greatest factor on earth. The group of videos introduces factoring polynomials by finding the greatest common factor (GCF). They connect finding the GCF of the terms in a polynomial to finding the GCF of two...

What is the greatest common factor of two terms in an expression? First prime factor each of the terms. Then find the factors that they have in common. Multiply if needed. That is how to find the greatest common factor. Watch the video...

Help! The leading coefficient is not one. Learners view a video showing a technique to factor trinomials when the leading coefficient is not one. Pupils try a few examples including solving equations by factoring and check their answers...

What's the opposite of multiplying binomials? Learners apply their previous knowledge of multiplying binomials using algebra tiles to factor trinomials. The instructional activity introduces factoring as a process that uses algebra tiles...

Use prime factorization to find the greatest common factor of three given values. Okay. But what if there doesn't seem to be any integer that is common in all three given values? Well, then, the greatest common factor must be 1. Not sure...

Use prime factorization to find the greatest common factor of four given values. What are the factors that all four given values have in common? Identify them, and then multiply together to get the greatest common factor. Just like that....

So you are looking for all the possible binomial factors of a trinomial expression? First find the factors of the coefficients. Then set up a table or template to do a guess and check. Write out, using the template, all the possible...
