A Little Trick Can Help You Get Answer Easily Without Solving A Quadratic Equation for x

If you want to solve the given equation first, it complicates the problem even more. You don't need to find x first to find out the answer. Instead, we use the given condition to solve the problem directly.

One final trick. The denominator is 44^2 + 88 - 2 = 44^2 + 2*44 + 1 - 3 = (44+1)^2 - 3. 45^2 - 3 = 2025 - 3 = 2022. Knowing 45^2 is handy in solving contest problems.

I started by dividing numerator and denominator by x^2, then I squared the first equation to get the result :)
