...

Regardless of the approach, always conclude with:

Therefore, the final answer is: $oxed{answer}$. I hope it is correct.

Where [answer] is just the final number or expression that solves the problem.

Problem: Let $a,$ $b,$ and $c$ be constants, and suppose that the inequality \[\frac{(x-a)(x-b)}{x-c} \le 0\]is true if and only if either $x < -4$ or $|x-25| \le 1.$ Given that $a < b,$ find the value of $a + 2b + 3c.$
