Introduction

When it comes to solving algebraic expressions, one of the most common operations is multiplication. In this article, we will explore how to use a table to find the product of two binomials, specifically ${$ (c-6)(c-5)$}$. This method is a great way to simplify complex expressions and make them more manageable.

What is a Binomial?

Before we dive into the solution, let's define what a binomial is. A binomial is an algebraic expression consisting of two terms. In the case of ${$ (c-6)(c-5)$}$, we have two binomials: ${$ (c-6)$}$ and ${$ (c-5)$}$.

The FOIL Method

One of the most common methods for multiplying binomials is the FOIL method. FOIL stands for First, Outer, Inner, Last, and it refers to the order in which we multiply the terms.

First

The first term in the first binomial is ${$ c$}$, and the first term in the second binomial is ${$ c$}$. When we multiply these two terms, we get ${$ c \cdot c = c^2$}$.

Outer

The outer terms are ${$ c$}$ from the first binomial and ${$ -5$}$ from the second binomial. When we multiply these two terms, we get ${$ c \cdot -5 = -5c$}$.

Inner

The inner terms are ${$ -6$}$ from the first binomial and ${$ c$}$ from the second binomial. When we multiply these two terms, we get ${$ -6 \cdot c = -6c$}$.

Last

The last term is ${$ -6$}$ from the first binomial and ${$ -5$}$ from the second binomial. When we multiply these two terms, we get ${$ -6 \cdot -5 = 30$}$.

Using a Table to Find the Product

Now that we have multiplied the terms using the FOIL method, let's use a table to find the product.

Term	First Binomial	Second Binomial	Product
1	${$ c$}$	${$ c$}$	${$ c^2$}$
2	${$ c$}$	${$ -5$}$	${$ -5c$}$
3	${$ -6$}$	${$ c$}$	${$ -6c$}$
4	${$ -6$}$	${$ -5$}$	${ $30\$}$

Combining Like Terms

Now that we have multiplied the terms using the FOIL method and used a table to find the product, let's combine like terms.

${$ c^2 - 5c - 6c + 30$}$

We can combine the like terms ${-5c}$ and ${-6c}$ to get ${-11c}$ .

${$ c^2 - 11c + 30$}$

Conclusion

In this article, we used a table to find the product of two binomials, specifically ${$ (c-6)(c-5)$}$. We first multiplied the terms using the FOIL method and then used a table to find the product. Finally, we combined like terms to simplify the expression. This method is a great way to simplify complex expressions and make them more manageable.
