Best ResponseYou've already chosen the best response.0I'm not sure if it is \[a+\sqrt{a+1}\] or \[a\sqrt{a1}\] the lesson I had is not very clear.

Best ResponseYou've already chosen the best response.1You're welcome. \((a  \sqrt{a  1})(a + \sqrt{a  1})\) follows the pattern \((a  b)(a + b) = a^2 + b^2\) The root term will disappear after multiplication. If you change the sign inside the root, it no longer follows the pattern of the product of a sum and a difference and the root terms will still be there after multiplication.
