Introduction

In this article, we will delve into a mathematical problem that involves solving a quadratic equation. The equation $n^2 + m^2 = 3nm$ is given, and we are asked to find the quotient $\frac{n+m}{n-m}$ . This problem requires us to manipulate the given equation, factorize it, and then solve for the values of $n$ and $m$ . We will use algebraic techniques to simplify the equation and find the required quotient.

The Quadratic Equation

The given equation is $n^2 + m^2 = 3nm$ . We can rewrite this equation as $n^2 - 3nm + m^2 = 0$ . This is a quadratic equation in terms of $n$ and $m$ . We can factorize this equation using the quadratic formula or by completing the square.

Factorizing the Quadratic Equation

We can factorize the quadratic equation $n^2 - 3nm + m^2 = 0$ as follows:

$n^2 - 3nm + m^2 = (n - m)^2 = 0$

This implies that $(n - m) = 0$ or $(n - m) = \pm \sqrt{0} = 0$ . Therefore, we have $n = m$ .

Solving for n and m

Since $n = m$ , we can substitute $m$ for $n$ in the original equation $n^2 + m^2 = 3nm$ . This gives us:

$m^2 + m^2 = 3m^2$

Simplifying this equation, we get:

$2m^2 = 3m^2$

Subtracting $2m^2$ from both sides, we get:

$0 = m^2$

This implies that $m = 0$ .

Finding the Quotient

Now that we have found the values of $n$ and $m$ , we can find the quotient $\frac{n+m}{n-m}$ . Since $n = m$ , we have:

$\frac{n+m}{n-m} = \frac{m+m}{m-m} = \frac{2m}{0}$

This is an indeterminate form, and we need to find the limit as $m$ approaches 0.

Finding the Limit

We can find the limit of $\frac{2m}{0}$ as $m$ approaches 0 by using L'Hopital's rule. This rule states that if we have an indeterminate form of the type $\frac{0}{0}$ or $\frac{\infty}{\infty}$ , we can find the limit by taking the derivative of the numerator and the denominator separately.

Applying L'Hopital's rule, we get:

$\lim_{m \to 0} \frac{2m}{0} = \lim_{m \to 0} \frac{2}{0}$

This is still an indeterminate form, and we need to apply L'Hopital's rule again.
