Sure, here is a beginner's problem to solve for somebody who wants to learn pre-calculus without providing the solution:

Solve for the roots of the quadratic equation:
x^2 - 2x + 1 = 0

This is a simple example of a beginner's problem in pre-calculus. The roots of the quadratic equation are the values of x that make the equation equal to 0. You can solve for the roots using the quadratic formula, but I will leave that up to you.

I hope this helps!
