Simplifying Quadratic Equations: Transforming 2x2 - 4x 2 into y ax - k2 c

When dealing with algebraic expressions, especially those involving quadratic equations, you may frequently need to simplify them to better understand their underlying structure. In this article, we will explore the process of transforming the given equation y 2x2 - 4x 2 into a simpler form of y ax - k2 c. This process is particularly useful for gaining insights into the fundamental components of a quadratic equation, such as its roots, vertex, and axis of symmetry.

Understanding the Given Equation

The given equation is y 2x2 - 4x 2. Let's break it down step by step to transform it into the desired form.

Step 1: Identify the Coefficients and Constants

In the equation y 2x2 - 4x 2, the coefficient of the x2 term is 2, the coefficient of the x term is -4, and the constant term is 2.

Step 2: Complete the Square

To transform the given equation into a simpler form, we will complete the square for the x terms.

First, factor out the coefficient of the x2 term from the x terms:

y 2(x2 - 2x 1)

Now, rewrite the expression inside the parentheses:

y 2(x2 - 2x 1)

This expression can be written as:

y 2(x - 1)2

Step 3: Adjust the Equation

Now, we can express the equation in the form y ax - k2 c. To do this, we need to adjust the equation further:

y 2(x - 1)2 - 2(0)

This simplifies to:

y 2(x - 1)2 - 2 * 0

Since -2(0) is just 0, the equation simplifies to:

y 2(x - 1)2

Step 4: Extract the Values of a, k, and c

From the equation y 2(x - 1)2, we can extract the values of a, k, and c:

a 2 k 1 c 0

Conclusion

Overall, the process of transforming the given equation y 2x2 - 4x 2 into the form y ax - k2 c involves the following steps:

Complete the square for the x terms. Factor out the coefficient of the x2 term. Adjust the equation to fit the desired form. Extract the values of a, k, and c.

By following these steps, you can simplify complex quadratic equations and gain a deeper understanding of their underlying components. This method is particularly useful in algebra and can help streamline problem-solving processes in various mathematical applications.
