Best ResponseYou've already chosen the best response.21 step is okay yes we can square root both sides no problem right?

Best ResponseYou've already chosen the best response.2oh that's second step not first

Best ResponseYou've already chosen the best response.2first is just equation itself

Best ResponseYou've already chosen the best response.2so 1 and 2 no problem

Best ResponseYou've already chosen the best response.1Do you think there is a fault in the 3rd step?

Best ResponseYou've already chosen the best response.23 now what do you think

Best ResponseYou've already chosen the best response.2look at one side of the equation at a time

Best ResponseYou've already chosen the best response.0sorry, my laptop is lagging,and it step 3 looks fine to me:S

Best ResponseYou've already chosen the best response.2hehe can we do this \(\sqrt{a^2+b^2}=a+b?\)

Best ResponseYou've already chosen the best response.1Well as @xapproachesinfinity said the R.H.S is fine as \[\sqrt{c^2} = c \] as they cancel

Best ResponseYou've already chosen the best response.2yes it is not allowed

Best ResponseYou've already chosen the best response.1But it should be something like \[\sqrt{(a+b)^2}\] to become a+b

Best ResponseYou've already chosen the best response.2right hand side :)

Best ResponseYou've already chosen the best response.1So to get that we know that we want something like \[\sqrt{a^2+2ab+b^2}\]

Best ResponseYou've already chosen the best response.2for this \(\sqrt{b^2+a^2}\) we cannot do anything to it

Best ResponseYou've already chosen the best response.2yes we can't as far as the problem is concerned!

Best ResponseYou've already chosen the best response.1We can solve it by adding root(2ab) on both sides?

xapproachesinfinity

Best ResponseYou've already chosen the best response.2hmm you meant \(c+\sqrt{2ab}=\sqrt{a^2+b^2}+\sqrt{2ab }\)

Best ResponseYou've already chosen the best response.2is that what you saying ?

Best ResponseYou've already chosen the best response.1No that won't do but we can add something to it so it becomes root(a^2+b^2+2ab)

xapproachesinfinity

Best ResponseYou've already chosen the best response.2you can't you add 2ab under the root so you must subtract it under the root

Best ResponseYou've already chosen the best response.1Well we shouldn't had done this step in the first place lol :p

Best ResponseYou've already chosen the best response.2this problem we need to go back to a^2+b^2=c^2 solve a a^2=c^2b^2 take root root(a^2)=root(c^2b^2) a=root(c^2b^2) a=+root(c^2b^2) the correct approach

hba

Best ResponseYou've already chosen the best response.1We could have done something like a^2 = c^2  b^2 so we'd get a= root(c^2b^2) for an answer

Best ResponseYou've already chosen the best response.1Lol we just wrote the samething

Best ResponseYou've already chosen the best response.2but we need + too

Best ResponseYou've already chosen the best response.2eh i didn;t read that positive reals part lol

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.2so it has to be a=root(c^2b^2)

Best ResponseYou've already chosen the best response.0yall are arguing a question which you both know but are not helping the actual person who needs help, both of u just completly confused me

Best ResponseYou've already chosen the best response.2ok now we need to promptly do this problem first step checked second step no we need to solve for a^2 third step square rroot both sides 4th step a=... that is it

Best ResponseYou've already chosen the best response.1I'm just gonna leave @xapproachesinfinity is here

Best ResponseYou've already chosen the best response.2look at my comment before this i did the problem

xapproachesinfinity

Best ResponseYou've already chosen the best response.2first step is okay 2 step no ( we need to isolate a^2 in one side) 3 step (no that's not allowed) (suggest take square root of both side of this equation a^2=c^2b^2) 4 step no (since third is wrong 4 will also be wrong) (suggested a=root(c^2b^2)) done!

Best ResponseYou've already chosen the best response.2no problem
