Introduction

Solving quadratic equations is a fundamental concept in mathematics, and it is essential to understand how to approach these types of problems. In this article, we will focus on solving the quadratic equation $v^2 - 13v = 0$ and present the solutions in their simplest form.

Understanding the Equation

The given equation is a quadratic equation in the form of $ax^2 + bx + c = 0$, where $a = 1$, $b = -13$, and $c = 0$. To solve this equation, we can use the factoring method, the quadratic formula, or the completing the square method. In this case, we will use the factoring method to find the solutions.

Factoring the Equation

To factor the equation $v^2 - 13v = 0$, we need to find two numbers whose product is $0$ and whose sum is $-13$. These numbers are $0$ and $-13$, so we can write the equation as:

$v(v - 13) = 0$

Finding the Solutions

Now that we have factored the equation, we can find the solutions by setting each factor equal to zero and solving for $v$. This gives us two possible solutions:

$v = 0$ or $v - 13 = 0$

Solving for $v$

To solve for $v$, we can add $13$ to both sides of the second equation:

$v = 13$

Combining the Solutions

Now that we have found the two solutions, we can combine them into a single expression:

$v = 0, 13$

Conclusion

In this article, we have solved the quadratic equation $v^2 - 13v = 0$ using the factoring method. We have found two solutions, $0$ and $13$, and presented them in their simplest form. This type of problem is essential in mathematics, and understanding how to solve quadratic equations is crucial for success in various fields.

Q: What is a quadratic equation?

A: A quadratic equation is a polynomial equation of degree two, which means that the highest power of the variable is two. It is typically written in the form of $ax^2 + bx + c = 0$, where $a$, $b$, and $c$ are constants.

Q: How do I solve a quadratic equation?

A: There are several methods for solving quadratic equations, including factoring, the quadratic formula, and completing the square. The method you choose will depend on the specific equation and the type of solution you are looking for.

Q: What is the quadratic formula?

A: The quadratic formula is a method for solving quadratic equations of the form $ax^2 + bx + c = 0$. It is given by the formula: $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$.

Q: How do I use the quadratic formula?

A: To use the quadratic formula, simply plug in the values of $a$, $b$, and $c$ into the formula and simplify. You will get two solutions, which are the values of $x$ that satisfy the equation.

Q: What is completing the square?
