Best ResponseYou've already chosen the best response.0Why would it be the conjugate of the numerator and not the denominator? Shouldn't it be multiplied by \[\frac{ \sqrt{a}+2\sqrt{y} }{ \sqrt{a}+2\sqrt{y} }\]

Best ResponseYou've already chosen the best response.3it should be \[\frac{ \sqrt{a} + 2\sqrt{y} }{ \sqrt{a}  2\sqrt{y}} \times \frac{ \sqrt{a} + 2\sqrt{y} }{ \sqrt{a} + 2\sqrt{y}}\]

Best ResponseYou've already chosen the best response.0Ok so that's the part I always have trouble with. I'm not the best at multiplying radicals.

Best ResponseYou've already chosen the best response.3\[(a  b) \times (a + b) = a^2  b^2 \]

Best ResponseYou've already chosen the best response.3so it would be \[\frac{ (\sqrt{a} + 2\sqrt{y})^2 }{ (\sqrt{a})^2  (2\sqrt{y})^2 }\]

Best ResponseYou've already chosen the best response.0Ok so @rishavraj then its simplified to get \[\frac{ a+2y }{ a2y }\] or would those 2s be a 4s?

Best ResponseYou've already chosen the best response.3\[(2\sqrt{y})^2 = 4y ~~~~ and ~~~(a + b)^2 = a^2 + b^2 + 2ab\]

Best ResponseYou've already chosen the best response.3and \[(\sqrt{a} + 2\sqrt{y})^2 = (\sqrt{a})^2 + (2\sqrt{y})^2 + 2 \times \sqrt{a} \times 2\sqrt{y}\]

Best ResponseYou've already chosen the best response.0Why the \[+2\times \sqrt{a}\times \sqrt{y}2\]

anonymous

Best ResponseYou've already chosen the best response.0I mean \[2\sqrt{y}\]
