Answer:
( 30 - 12√6 )
Step-by-step explanation:
Given :- The given expression is (2√3 - 3√2)²
To Find :- The value of (2√3 - 3√2)²
Solution :-
The given expression is (2√3 - 3√2)²
We know that,
( a - b )² = a² + b² - 2 × a × b
(2√3 - 3√2)² = ( 2√3 )² + ( 3√2 )² - 2( 2√3 )( 3√2 )
= ( 2√3 )( 2√3 ) + ( 3√2 )( 3√2 ) - 2( 2√3 )( 3√2 )
= 4 × 3 + 9 × 2 - 2 × 6√6
= 12 + 18 - 12√6
= 30 - 12√6
Therefore, the value of (2√3 - 3√2)² is 30 - 12√6 .
