How do you use the Quadratic Formula to solve First Order ODE?

Click For Summary
To solve a first-order ordinary differential equation (ODE) using the Quadratic Formula, first integrate both sides of the equation. After integration, rearrange the equation to form a standard quadratic equation. Treat the term t^2 + k as a constant when applying the Quadratic Formula. This approach allows for expressing y in terms of t effectively. Understanding how to manipulate the equation is key to finding the solution.

Homework Statement



How do you use the Quadratic Formula to solve First Order ODE?

For example, I am given this integration (see attachment at the bottom).

The Attempt at a Solution



I integrated both sides but I do not know where to go from there (see attachment at the bottom). My goal is to express y in terms of t. Furthermore, my book says I should use the Quadratic Formula to figure it out. I know what the Quadratic Formula is, but I do not know how to apply it in this situation. Can anyone give me any hints? Thanks.

Treat the t^2 + k as any other constant. Bring it over and you have a quadratic equation like any other.

I see. 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?
