To simplify the expression [4 - 2√5]/2, we can follow these steps:
Given expression:
[4 - 2√5]/2
Step 1: Factor out the common factor of 2 in the numerator.
[2(2 - √5)]/2
Step 2: Cancel out the common factor of 2 in the numerator and denominator.
[2 - √5]
So, the simplified form of the expression [4 - 2√5]/2 is 2 - √5.
