Sure, in simpler terms:
Given that the distance between the points (4, 1) and (3, a) is √10, we can set up the distance formula:
√10 = √((3 - 4)^2 + (a - 1)^2).
Solving this equation, we get:
8 = a^2 - 2a.
This is a quadratic equation for \(a\), which can be solved to find the possible values of \(a\).
