Best ResponseYou've already chosen the best response.1Multiply and divide both the sides by: \[\sqrt{x+4}\sqrt{x 3}\]

Best ResponseYou've already chosen the best response.1You mean multiply by \[(\sqrt{x+4}  \sqrt{x3})/(\sqrt{x+4}  \sqrt{x3})\]

Best ResponseYou've already chosen the best response.1just do what @georgeblue22 said.. I was thinking it as an expression but it is an equation.. I forgot to see there 1 on right hand side...

Best ResponseYou've already chosen the best response.1Oh yes, he brought the denominator to the other side.

Best ResponseYou've already chosen the best response.1See, multiply both the sides by : \(\sqrt{x+4}+\sqrt{x 3}\)..

Best ResponseYou've already chosen the best response.1That will help to get of the square root on the left side.

Best ResponseYou've already chosen the best response.1Understood @pratu043 ??? :)

Best ResponseYou've already chosen the best response.1You will left with only one square root term.... after solving..

Best ResponseYou've already chosen the best response.0Did you try squaring on both the sides ?

Best ResponseYou've already chosen the best response.1See show me what you get after multiply the term I said above... Do it slowly...

Best ResponseYou've already chosen the best response.1So 7 = sqrt(x + 4) + sqrt(x  3).

Best ResponseYou've already chosen the best response.1\[\frac{(\sqrt{x+4}  \sqrt{x3})}{(\sqrt{x+4} + \sqrt{x3})} \times (\sqrt{x+4} + \sqrt{x3}) = 1 \times (\sqrt{x+4} + \sqrt{x3})\] Now solve this..

Best ResponseYou've already chosen the best response.1You will be left with: \[\sqrt{x+4} \sqrt{x3} = \sqrt{x+4} + \sqrt{x3}\] Now look it properly what is the term that is getting cancelling on both the sides???

waterineyes

Best ResponseYou've already chosen the best response.1Yes then cancel it and tell me what you are left with now..

waterineyes

Best ResponseYou've already chosen the best response.1Can you bring them on one side now??

waterineyes

Best ResponseYou've already chosen the best response.1Yes... Have faith you are in a right direction.. Now squaring both the sides what will you get??

Best ResponseYou've already chosen the best response.1sqaure both sides @pratu043

waterineyes

Best ResponseYou've already chosen the best response.1And then put the brackets = 0 and find x from here..

waterineyes

Best ResponseYou've already chosen the best response.1Yes.. You are right...

Best ResponseYou've already chosen the best response.1yes @pratu043 u got it ;) deserve a medal ;)

Best ResponseYou've already chosen the best response.1See @pratu043 if we are given with: \[\large (x1)(y2) = 0\] then you can do directly this: \[(x  1) =0 \quad and \quad (y  2) = 0\] Getting???

Best ResponseYou've already chosen the best response.1So at the end we are left with: \[4(x3) = 0\] As \(4 \ne 0\) So, You can put directly: \[(x3) = 0\] \[x = 3\]

Best ResponseYou've already chosen the best response.1Oh I see .... I never knew that.

Best ResponseYou've already chosen the best response.1But this is possible in case we have 0 in right hand side.. Be careful...
