How Do You Factor a Trinomial?

Students investigate polynomials. In this algebra lesson, students solve problems dealing with multiplication of polynomials by using the distributive property and the FOIL method. Students also describe how the...

Help learners study polynomials. They will review how to multiply polynomials either by using the FOIL method if they are multiplying a binomial by another binomial, or by using the distributive property.

There are very specific ways to multiply binomials. One could use the FOIL method or employ the distributive property. Sal walks through each step of the FOIL method and then shows that using distribution results in the same answer. This...

Use division and factoring to determine the leading 1 coefficient. This presentation thoroughly explains how to factor a trinomial in order to determine its common factors.

Here is a complete and clear demonstration of the process needed to factor a trinomial with a non-1 leading coefficient. Sal uses various colors and provides working examples while he factors the simple trinomial. This video would be...

Find the area of FOIL. A short video makes the connection between the FOIL method and the area model of multiplying two binomials. The graphics show how the different parts of the area model can be connected to the nemonic FOIL.

Have you ever heard of the FOIL method? Watch and learn how the FOIL method can be used to help you multiply binomials. It all starts with a tic-tac-toe box and two polynomials then ends with a correct answer.

FOIL it! What? You want to multiply two binomials then use the FOIL method: First, Outside, Inside, Last. When you have done that, your final steps is to combine the like terms.

FOIL it! What? You want to multiply two binomials then use the FOIL method: First, Outside, Inside, Last. When you have done that, your final step is to combine the like terms.

FOIL= first, outside, inside, last. Use this method to multiply two binomials. The teacher demonstrates this method using variables. Then she demonstrates with numbers and variables and writes out each term being multiplied. Finally,...
