Introduction

Quadratic equations are a fundamental concept in mathematics, and factoring them is a crucial skill to master. In this article, we will delve into the world of quadratic equations and explore the process of factoring completely. We will use the equation $2x^2 - 40x + 200 = 0$ as a case study to demonstrate the step-by-step process of factoring completely.

What is Factoring Completely?

Factoring completely is the process of expressing a quadratic equation in the form of $(ax + b)(cx + d) = 0$ , where $a$ , $b$ , $c$ , and $d$ are constants. This process involves finding two binomials that, when multiplied together, result in the original quadratic equation.

The Process of Factoring Completely

To factor completely, we need to follow a series of steps:

Check if the quadratic equation can be factored: Before we start factoring, we need to check if the quadratic equation can be factored. We can do this by checking if the equation has any common factors.
Find the greatest common factor (GCF): If the equation has any common factors, we need to find the greatest common factor (GCF) of the coefficients.
Write the equation in the form of $ax^2 + bx + c = 0$ : We need to write the equation in the standard form of a quadratic equation, which is $ax^2 + bx + c = 0$ .
Find two binomials that multiply to the original equation: We need to find two binomials that, when multiplied together, result in the original quadratic equation.
Simplify the expression: Once we have found the two binomials, we need to simplify the expression by combining like terms.

Factoring the Equation $2x^2 - 40x + 200 = 0$

Now that we have understood the process of factoring completely, let's apply it to the equation $2x^2 - 40x + 200 = 0$ .

Step 1: Check if the quadratic equation can be factored

The equation $2x^2 - 40x + 200 = 0$ can be factored because it has a common factor of 2.

Step 2: Find the greatest common factor (GCF)

The GCF of the coefficients is 2.

Step 3: Write the equation in the form of $ax^2 + bx + c = 0$

The equation can be written as $2x^2 - 40x + 200 = 0$ .

Step 4: Find two binomials that multiply to the original equation

We need to find two binomials that, when multiplied together, result in the original quadratic equation. Let's try to find two binomials that multiply to $2x^2 - 40x + 200$ .

After some trial and error, we find that the two binomials are $(2x - 10)(x - 20)$ .

Step 5: Simplify the expression

We can simplify the expression by combining like terms:

$(2x - 10)(x - 20) = 2x^2 - 40x + 200$

The final answer is $\boxed{(2x - 10)(x - 20)}$ .

Conclusion

Factoring completely is a crucial skill in mathematics, and it requires a deep understanding of quadratic equations. By following the steps outlined in this article, we can factor completely any quadratic equation. We used the equation $2x^2 - 40x + 200 = 0$ as a case study to demonstrate the process of factoring completely.
