Introduction

Factorizing quadratic expressions is a fundamental concept in algebra that helps us simplify complex equations and solve problems more efficiently. In this article, we will focus on factorizing the quadratic expression $$6x^2 + x - 12$$, and provide a step-by-step guide on how to do it.

What is Factorization?

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

The Factorization Process

To factorize a quadratic expression, we need to follow a series of steps:

Check if the expression can be factored by grouping: If the expression can be grouped into two parts, we can factor out the common factor from each part.
Check if the expression can be factored using the difference of squares formula: If the expression is in the form $$a^2 - b^2$$, we can factor it using the difference of squares formula.
Check if the expression can be factored using the sum of squares formula: If the expression is in the form $$a^2 + b^2$$, we can factor it using the sum of squares formula.
Check if the expression can be factored using the product of two binomials: If the expression is in the form $$a(x + b)(x + c)$$, we can factor it using the product of two binomials.

Factorizing the Expression $$6x^2 + x - 12$$

To factorize the expression $$6x^2 + x - 12$$, we can start by checking if it can be factored by grouping. We can group the first two terms together and the last two terms together:

6x^2 + x - 12 = (6x^2 + x) - 12

Now, we can factor out the common factor from each group:

6x^2 + x - 12 = 6x(x + \frac{1}{6}) - 12

However, this does not help us factorize the expression further. Let's try to factorize it using the difference of squares formula. Unfortunately, the expression is not in the form $$a^2 - b^2$$, so we cannot use this formula.

Next, let's try to factorize it using the sum of squares formula. Unfortunately, the expression is not in the form $$a^2 + b^2$$, so we cannot use this formula.

Finally, let's try to factorize it using the product of two binomials. We can write the expression as:

6x^2 + x - 12 = (3x + 4)(2x - 3)

Therefore, the factorized form of the expression $$6x^2 + x - 12$$ is $$(3x + 4)(2x - 3)$$.

Conclusion

In this article, we have factorized the quadratic expression $$6x^2 + x - 12$$ using the product of two binomials. We have also provided a step-by-step guide on how to factorize quadratic expressions.

Introduction

In our previous article, we discussed the concept of factorizing quadratic expressions and provided a step-by-step guide on how to do it. However, we understand that sometimes, it's not enough to just read about a concept, but rather to have a chance to ask questions and clarify any doubts. In this article, we will provide a Q&A guide on factorizing quadratic expressions, where we will answer some of the most frequently asked questions on this topic.

Q: What is factorization?

A: Factorization is the process of expressing an algebraic expression as a product of simpler expressions, called factors. In the case of quadratic expressions, we can factorize them into the product of two binomial expressions.

Q: How do I factorize a quadratic expression?

A: To factorize a quadratic expression, you need to follow a series of steps:

Check if the expression can be factored by grouping: If the expression can be grouped into two parts, you can factor out the common factor from each part.
Check if the expression can be factored using the difference of squares formula: If the expression is in the form $$a^2 - b^2$$, you can factor it using the difference of squares formula.
Check if the expression can be factored using the sum of squares formula: If the expression is in the form $$a^2 + b^2$$, you can factor it using the sum of squares formula.

Q: What is the difference of squares formula?

A: The difference of squares formula is a formula that allows us to factorize expressions in the form $$a^2 - b^2$$ into the product of two binomials. The formula is:

a^2 - b^2 = (a + b)(a - b)

Q: What is the sum of squares formula?

A: The sum of squares formula is a formula that allows us to factorize expressions in the form $$a^2 + b^2$$ into the product of two binomials. However, there is no simple formula for this, and we need to use other methods to factorize these expressions.

Q: How do I factorize an expression using the product of two binomials?

A: To factorize an expression using the product of two binomials, you need to write the expression in the form $$a(x + b)(x + c)$$. Then, you can factor out the common factor from each part:

a(x + b)(x + c) = a(x + b)(x + c)
