Forty-five channel link [_________] devices arranged in a fully connected mesh topology; Nine, Ten, Forty, Forty-five-one?
Start by multiplying both sides by 2 to get rid of the fraction: \[ 2L_N = N(N - 1) \]
Expand the right side: \[ 2L_N = N^2 - N \]
Rearrange the equation to form a standard quadratic equation: \[ N^2 - N - 2L_N = 0 \]
Solve this quadratic equation using the quadratic formula \( N = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \), where \( a = 1 \), \( b = -1 \), and \( c = -2L_N \): \[ N = \frac{-(-1) \pm \sqrt{(-1)^2 - 4 \cdot 1 \cdot (-2L_N)}}{2 \cdot 1} \] \[ N = \frac{1 \pm \sqrt{1 + 8L_N}}{2} \]
So, the solutions for \( N \) are: \[ N = \frac{1 + \sqrt{1 + 8L_N}}{2} \quad \text{or} \quad N = \frac{1 - \sqrt{1 + 8L_N}}{2} \]
Since \( N \) represents a count, we typically take the positive solution: \[ N = \frac{1 + \sqrt{1 + 8L_N}}{2} \]
