Introduction

In algebra, factoring quadratic expressions is a crucial skill that helps us simplify complex equations and solve problems more efficiently. When we factor a quadratic expression, we break it down into simpler components, making it easier to work with. In this article, we will explore how to factor a quadratic expression represented by the diagram, which includes a factor of $2x - 1$ .

Understanding the Diagram

The diagram represents the quadratic expression $6x^2 - 7x + 2$ with a factor of $2x - 1$ . To factor this expression, we need to understand the relationship between the quadratic expression and the given factor. The diagram provides a visual representation of this relationship, helping us identify the missing terms and coefficients.

Identifying the Missing Terms

Looking at the diagram, we can see that the first row represents the quadratic expression $6x^2 - 7x + 2$ . The second row represents the factor $2x - 1$ . To identify the missing terms, we need to multiply the factor by a suitable expression to obtain the quadratic expression.

Step 1: Multiply the Factor by a Suitable Expression

To multiply the factor $2x - 1$ by a suitable expression, we need to consider the coefficients of the quadratic expression. The coefficient of $x^2$ in the quadratic expression is 6, and the coefficient of $x$ in the factor is 2. We can multiply the factor by $3x$ to obtain the coefficient of $x^2$ .

(2x - 1) × 3x = 6x^2 - 3x

Step 2: Identify the Missing Term

Now that we have obtained the coefficient of $x^2$ , we need to identify the missing term. Looking at the diagram, we can see that the missing term is $-4x$ . This term is obtained by multiplying the factor $2x - 1$ by $-2$ .

(2x - 1) × (-2) = -4x

Step 3: Identify the Constant Term

Finally, we need to identify the constant term. Looking at the diagram, we can see that the constant term is 2. This term is obtained by multiplying the factor $2x - 1$ by 1.

(2x - 1) × 1 = 2

Conclusion

In conclusion, we have successfully factored the quadratic expression $6x^2 - 7x + 2$ with a factor of $2x - 1$ . By understanding the relationship between the quadratic expression and the given factor, we were able to identify the missing terms and coefficients. This process helps us simplify complex equations and solve problems more efficiently.

The Final Answer

The final answer is:

\boxed{(2x - 1)(3x - 2)}
