Introduction

Factorizing expressions is a fundamental concept in mathematics that involves breaking down an algebraic expression into simpler components. In this article, we will focus on factorizing the expression $$36 + 30$$. Our goal is to rewrite this expression in the form $$a(b+c)$$, where $$a$$ is the greatest common factor (GCF) of 36 and 30.

Understanding Greatest Common Factor (GCF)

Before we proceed with factorizing the expression, let's understand what GCF is. The GCF of two numbers is the largest positive integer that divides both numbers without leaving a remainder. In this case, we need to find the GCF of 36 and 30.

Finding the GCF of 36 and 30

To find the GCF of 36 and 30, we can list the factors of each number and identify the common factors.

Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30

From the list of factors, we can see that the common factors of 36 and 30 are 1, 2, 3, and 6. Therefore, the GCF of 36 and 30 is 6.

Factorizing the Expression

Now that we have found the GCF of 36 and 30, we can factorize the expression $$36 + 30$$. We will rewrite the expression in the form $$a(b+c)$$, where $$a$$ is the GCF of 36 and 30.

36 + 30 = 6(6+5)

In this expression, $$6$$ is the GCF of 36 and 30, and $$(6+5)$$ is the sum of the two numbers.

Simplifying the Expression

We can simplify the expression further by evaluating the sum inside the parentheses.

6(6+5) = 6(11)

Therefore, the final factorized form of the expression $$36 + 30$$ is $$6(11)$$.

Conclusion

In this article, we factorized the expression $$36 + 30$$ in the form $$a(b+c)$$, where $$a$$ is the GCF of 36 and 30. We found that the GCF of 36 and 30 is 6, and the factorized form of the expression is $$6(11)$$. This demonstrates the importance of understanding the concept of GCF and how it can be applied to factorize expressions.

Real-World Applications

Factorizing expressions has numerous real-world applications in various fields, including mathematics, science, and engineering. For example, in algebra, factorizing expressions is used to solve equations and inequalities. In calculus, factorizing expressions is used to find the derivative and integral of a function. In physics, factorizing expressions is used to describe the motion of objects and the behavior of physical systems.

Tips and Tricks

Here are some tips and tricks to help you factorize expressions:

Use the distributive property: The distributive property states that $$a(b+c) = ab + ac$$. This property can be used to factorize expressions by expanding the expression and then factoring out the common terms.
Look for common factors: When factorizing an expression, look for common factors among the terms. This can help you identify the GCF and factorize the expression.
Use the GCF to factorize: The GCF of two numbers is the largest positive integer that divides both numbers without leaving a remainder. Use the GCF to factorize the expression by rewriting it in the form $$a(b+c)$$.

Common Mistakes to Avoid

Here are some common mistakes to avoid when factorizing expressions:

Not identifying the GCF: Failing to identify the GCF of two numbers can lead to incorrect factorization.
Not using the distributive property: Not using the distributive property can make it difficult to factorize expressions.
Not looking for common factors: Not looking for common factors can lead to incorrect factorization.
