More pls?? Rationalize the denominator and simplify. https://mvusdk12.owschools.com/media/g_alg02_ccss_2014/7/q11171.gif

hint... \[\frac{1}{\sqrt{a}+2\sqrt{y}}\]

OpenStudy (faiqraees):

okay do you know what rationalize means?

OpenStudy (faolan):

nope

OpenStudy (faolan):

got it "to remove radicals in the denominator by changing the fraction to an equal expression with a rational denominator

OpenStudy (faiqraees):

yeah to make the denominator rational. So applying the identity \[(a+b)(a-b)=a^2-b^2\] we have to multiply \[\sqrt{a}-2\sqrt{y}\] to both the numerator and denominator . Can you do that?

OpenStudy (faolan):

ill try

OpenStudy (faolan):

i dont know what im doing..........
