Problem Statement
Esmeralda chooses two distinct positive integers and , with , and writes the equation on the board. If the equation has distinct positive integer roots and , with , she writes the equation on the board. She repeats the procedure as long as she obtains distinct positive integer roots. If she writes an equation for which this does not occur, she stops. a) Show that Esmeralda can choose and such that she will write exactly 2024 equations on the board.
b) What is the maximum number of equations she can write knowing that one of the initially chosen numbers is 2024?
