Ok so I know that when you have radicals such as the following you only have one answer right?...(adsbygoogle = window.adsbygoogle || []).push({});

x + 1 - 2(square root of [x+4]) = 0

ok so

x = 5 right?.... i dunno why but it just does... I cant solve it

If i solve it

It works looks like this:

(squaring everything I get this in the end)

x^2-2x-15=0

ok so the answers for x = 5 ORRRRRRRRRRRR x = -3????

why is this so... I must be doing this wrong.. but I dunno how its done=/ plz help.

if I graph them... the first one just is a l ine that just "ends" =/ and the other one is a parabula of course.
