Expressions with square roots (surds) often look complicated, but with the right approach, they become very simple. In this video, we solve the expression (√3 + 2)² + (√3 − 2)² and determine whether the result is rational or irrational.

Instead of expanding randomly, we use the identity (a + b)² + (a − b)² = 2(a² + b²). This shortcut helps us avoid lengthy calculations and makes the solution much faster. Applying this, the irrational terms cancel out, leaving us with a rational number.

This concept is very useful for students preparing for CBSE exams, school tests, and competitive exams, where simplification and logic play a key role. Learning these identities can save time and reduce mistakes in exams.
