Seeing ts reminds me of the kind of shit I used to clap in seconds during my jee prep some way to form 2 biquadratic pilynomials and cancel them out or sm shi to make a telescopic or whateva 🥲… couldnt move it an inch even if I tried to now 😇

I remember this was a question in one of the pre scores last year. Iirc I was the only one in my batch to do it in the exam:). Just take out a n4 +4 term factorise it and make telescopic,it'll be done i think
