Question

add. (2√3-5√2) (√3+2√2)​

Answer 1

Step-by-step explanation:

$(2 \sqrt{3} - 5 \sqrt{2} )( \sqrt{3} + 2 \sqrt{2} ) \\ (2 \sqrt{3} \times \sqrt{3} ) + (2 \sqrt{3} \times 2 \sqrt{2}) - (5 \sqrt{2} \times \sqrt{3} ) - (5 \sqrt{2} \times 2 \sqrt{2} )$

$6 + 4 \sqrt{6} - 5 \sqrt{6} - 20 = - (14 + \sqrt{6} )$
