Introduction

Factoring an expression is a crucial step in solving algebraic equations and inequalities. One of the methods used to factor an expression is the grouping method. This method involves rearranging the terms of the expression into groups that can be factored using the difference of squares or the sum and difference of two terms. In this article, we will arrange the steps from start to finish to factor the expression $x^2 - 5x - 24$ using the grouping method.

Step 1: Write Down the Expression

The given expression is $x^2 - 5x - 24$ . We will start by writing down the expression.

x^2 - 5x - 24

Step 2: Rearrange the Terms

To factor the expression using the grouping method, we need to rearrange the terms into two groups. We can do this by grouping the first two terms together and the last two terms together.

(x^2 - 5x) + (-24)

Step 3: Factor the First Group

The first group is $(x^2 - 5x)$ . We can factor out the common term $x$ from this group.

x(x - 5)

Step 4: Factor the Second Group

The second group is $(-24)$ . We can factor out the common term $-1$ from this group.

-1(-24)

Step 5: Rewrite the Expression

Now that we have factored the first and second groups, we can rewrite the expression as follows:

x(x - 5) - 1(-24)

Step 6: Factor the Expression

We can now factor the expression using the difference of squares formula.

(x - 3)(x + 8)

Conclusion

In this article, we have arranged the steps from start to finish to factor the expression $x^2 - 5x - 24$ using the grouping method. We started by writing down the expression, rearranging the terms, factoring the first group, factoring the second group, rewriting the expression, and finally factoring the expression using the difference of squares formula.

Discussion

The grouping method is a useful technique for factoring expressions. It involves rearranging the terms of the expression into groups that can be factored using the difference of squares or the sum and difference of two terms. This method can be used to factor a wide range of expressions, including quadratic expressions, polynomial expressions, and rational expressions.
