Best ResponseYou've already chosen the best response.0yes right multiply \[\huge\rm \frac{ (\sqrt{a} + 2\sqrt{y})(\sqrt{a}+2\sqrt{y}) }{ (\sqrt{a}2\sqrt{y})(\sqrt{a}+2\sqrt{y}) }\] multiply familiar with the foil method ?

Best ResponseYou've already chosen the best response.0or hint: \[\huge\rm (x+y)^2 = x^2 +2xy + y^2\] take square of first term take square of 2nd term and then multiply both term by 2

Best ResponseYou've already chosen the best response.0yes right multiply \[\large\rm \frac{ (\sqrt{a} + 2\sqrt{y})(\sqrt{a}+2\sqrt{y}) }{ (\sqrt{a}2\sqrt{y})(\sqrt{a}+2\sqrt{y}) }\] both parentheses are the same at the numerator so you can write it as \[\huge\rm \frac{ (\sqrt{a}+2\sqrt{y})^2 }{ (\sqrt{a}2\sqrt{y})(\sqrt{a}+2\sqrt{y}) }\] same like (x+y)^2
