Introduction

Quadratic equations are a fundamental concept in algebra, and solving them is a crucial skill for students to master. One of the methods used to solve quadratic equations is the zero product property. In this article, we will explore how to use the zero product property to find the solutions to the equation $$x^2 - 13x + 30 = 0$$.

What is the Zero Product Property?

The zero product property states that if the product of two or more factors is equal to zero, then at least one of the factors must be equal to zero. In other words, if $$ab = 0$$, then either $$a = 0$$ or $$b = 0$$ (or both). This property can be applied to quadratic equations to find the solutions.

Solving the Equation Using the Zero Product Property

To solve the equation $$x^2 - 13x + 30 = 0$$ using the zero product property, we need to factor the quadratic expression. The factored form of the equation is $$(x - 10)(x - 3) = 0$$. Now, we can apply the zero product property to find the solutions.

Step 1: Set Each Factor Equal to Zero

Using the zero product property, we set each factor equal to zero:

(x - 10) = 0

(x - 3) = 0

Step 2: Solve for x

Now, we solve for x by isolating the variable:

x - 10 = 0

x = 10

x - 3 = 0

x = 3

Conclusion

Therefore, the solutions to the equation $$x^2 - 13x + 30 = 0$$ are $$x = 10$$ or $$x = 3$$. This is option B.

Discussion

The zero product property is a powerful tool for solving quadratic equations. By factoring the quadratic expression and setting each factor equal to zero, we can find the solutions to the equation. In this case, we found that the solutions are $$x = 10$$ or $$x = 3$$. This is a great example of how the zero product property can be used to solve quadratic equations.

Common Mistakes

When using the zero product property to solve quadratic equations, there are a few common mistakes to watch out for:

Not factoring the quadratic expression correctly
Not setting each factor equal to zero
Not solving for x correctly

By avoiding these common mistakes, you can ensure that you are using the zero product property correctly to solve quadratic equations.

Real-World Applications

The zero product property has many real-world applications. For example, in physics, the zero product property can be used to solve equations that describe the motion of objects. In engineering, the zero product property can be used to solve equations that describe the behavior of electrical circuits.

Conclusion

In conclusion, the zero product property is a powerful tool for solving quadratic equations. By factoring the quadratic expression and setting each factor equal to zero, we can find the solutions to the equation. In this case, we found that the solutions are $$x = 10$$ or $$x = 3$$. This is a great example of how the zero product property can be used to solve quadratic equations.
