why did you choose to add 6y^2? can it be something else as long as we get a perfect square trinomial or...?

it's a algebra solving trick, I learn it in my 12th grade, where I learnt more techniques and procedures of trigonometry and other problem solving phenomenon. Most of problem and Solving Linear Equations With Fractions are also solved by using adding and subtracting.
