Sachin and Rahul attempted to solve a quadratic equation. Sachin made a mistake in writing down the constant term and ended up in roots \( (4,3) \). Rahul made a mistake in writing down coefficient of \( x \) to get roots \( (3,2) \). The correct roots of equation are [AIEEE 2011, 4M]https://bit.ly/YTAI_PWAP https://www.pw.live
