To solve the equation P + N = C + 2/C for C, it can be rearranged into a quadratic form: C^2 - C(N + P) - 2 = 0. This transformation allows the use of the quadratic formula to find the values of C. The discussion highlights the importance of recognizing the equation as a quadratic to apply the appropriate solving methods. The user expresses gratitude upon realizing the correct approach to solve the equation. Understanding how to manipulate equations into standard forms is crucial for solving quadratic equations effectively.

Write it as C^2-C(N+P)-2=0. It's a quadratic equation in C, right? How do you solve quadratics?

Oh okay, I use the quadratic formula. I understand now thanks!
 
Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
