What Numbers Go In The Gaps To Factorize The Expression?${ F^2 + 7f + 10 = \left(f + __\right)\left(f + __\right) }$

Introduction

Factorizing an algebraic expression is a fundamental concept in mathematics, and it plays a crucial role in solving equations and inequalities. In this article, we will focus on factorizing a quadratic expression of the form $f^2 + 7f + 10$. Our goal is to find the numbers that go in the gaps to factorize the expression.

Understanding the Concept of Factorization

Factorization is the process of expressing an algebraic expression as a product of simpler expressions, called factors. In the case of a quadratic expression, we can factorize it into two binomial factors. The general form of a quadratic expression is $ax^2 + bx + c$, and we can factorize it as $(x + p)(x + q)$, where $p$ and $q$ are the factors.

The Given Expression

The given expression is $f^2 + 7f + 10$. We need to find the numbers that go in the gaps to factorize this expression. To do this, we need to identify the factors of the constant term, which is 10.

Finding the Factors of 10

The factors of 10 are 1, 2, 5, and 10. We need to find two numbers whose product is 10 and whose sum is 7. These numbers are 2 and 5.

Factorizing the Expression

Now that we have found the factors of 10, we can factorize the expression as follows:

$f^2 + 7f + 10 = (f + 2)(f + 5)$

Explanation

To factorize the expression, we need to find two numbers whose product is 10 and whose sum is 7. We have already identified these numbers as 2 and 5. We can now rewrite the expression as $(f + 2)(f + 5)$.

Conclusion

In this article, we have factorized the expression $f^2 + 7f + 10$ as $(f + 2)(f + 5)$. We have identified the factors of 10 and used them to factorize the expression. This is a fundamental concept in mathematics, and it plays a crucial role in solving equations and inequalities.

Step-by-Step Solution

Here is a step-by-step solution to factorize the expression:

1. Identify the factors of the constant term, which is 10.
2. Find two numbers whose product is 10 and whose sum is 7.
3. Rewrite the expression as $(f + p)(f + q)$, where $p$ and $q$ are the factors.

Example

Let's consider an example to illustrate the concept of factorization. Suppose we have the expression $x^2 + 5x + 6$. We need to factorize this expression as $(x + p)(x + q)$, where $p$ and $q$ are the factors.

Solution

To factorize the expression, we need to find two numbers whose product is 6 and whose sum is 5. These numbers are 2 and 3. We can now rewrite the expression as $(x + 2)(x + 3)$.
