Hello steemian friends! Today's post discusses the steps on " How to find the Product of two Binomials using FOIL Method". Again, I made it sure that the language used in the presentation is user-friendly in the sense that it is easily understood by a reader who has at least an 8th-grade education (age 13-14).

In my 8<sup>th</sup> grader's classes, I did emphasize that there are many ways on how to find the product of two binomials. If the task is to square a binomial then the use of a pattern is the easiest and the shortest. One can even mentally do it since the answer is readily seen. (Yet only if one had mastered the operations on polynomials and the laws of exponent in finding its product.).

To my surprise!, most of my regular classes (regular class because we have a Science class and a Pilot class who are homogeneous and are fast learners.) feel comfortable in using the FOIL method in finding the product of two binomials even if it is a "Special Product". At times when I strictly imposed to them to only follow the pattern (since it is easier and shorter on special product) Nah! most of them failed.  So I need to look for another strategy, to somewhat meet them halfway (the one that would make the majority happy...haha!) And that is to let them used either method provided that we will arrive at the same answer. Alrigth, game!

<h3>What is FOIL method? - brief review</h3>
**FOIL** is just a mnemonic for the standard method of multiplying two binomials.
>F - means product of the first terms
 O - means product of the outer terms
  I  - means product of the inner terms
  L - means product of the last terms

So to apply this method, we need to recall first on the following.
 <center><h4>*So here!*</h4></center>
<center>Let **( a + b )**  and **( c + d )** be the two binomials, where,</center>

<h3>How to find the product of two binomials using FOIL method?</h3>
Let **( a + b )**  and **( c + d )** be the two binomials.

<h4>Here are the steps:</h4>
- Step 1. Find the product of the first terms ( **F** )

<h3>Conclusion</h3>

Note: It is important that one should be very careful in combining like terms. Good thing we only used positive integers here. Students usually overlooked signed numbers maybe because they don't have mastery in doing it, or they just got mistake due to carelessness.

So we're done! That's how we find the product of two binomials using **FOIL** method. Thanks for learning with me. Steem on!
