The video tutorial introduces a mathematical problem involving integers a and b with opposite signs. The problem requires solving two equations derived from given ratios to find the value of a^2/b^2. The tutorial walks through the process of deriving equations from the ratios, equating them, and solving for a and b. After discarding non-integer solutions, the correct values of a and b are found, leading to the final result of 25/4 for a^2/b^2.
