Question

simplify. ???????????​

Answer 1

Step-by-step explanation:

$( \sqrt{5} - \sqrt{7} )( \sqrt{5} + \sqrt{2} )$

Apply FOIL method...

$= > \sqrt{5 } \sqrt{5} + \sqrt{5} \sqrt{2} + ( - \sqrt{7} ) \sqrt{5} + ( - \sqrt{7} ) \sqrt{2}$

$= > \sqrt{5} \sqrt{5} + \sqrt{5} \sqrt{2} - \sqrt{7} \sqrt{5 - } \sqrt{7} \sqrt{2}$

Simplify...

$= > \huge5 + \sqrt{10} - \sqrt{35} - \sqrt{14}$
