Best ResponseYou've already chosen the best response.2there is a solution... but I'm trying to figure it out... unless we square both sides.. but that  has to be outside so it needs to be something like\[(x8)^2=(\sqrt{x ^{2}8})^2\] then on the right hand side distribute the negative for the left hand side expand

Best ResponseYou've already chosen the best response.2\[(x8)(x8)=(x^28) \] I'll do the easy part then you can do the hard one ^_^ \[(x8)(x8)=x^2+8 \]

Best ResponseYou've already chosen the best response.2once that is done.. get the variables to the left and put all numbers to the right

Best ResponseYou've already chosen the best response.2something is off. the denominator part is right.. but not the numerator... it's supposed to be x= 9/2

Best ResponseYou've already chosen the best response.0hint: we can rewrite the original equation as below: \[\Large \sqrt {{x^2}  8} = 8  x\]

Best ResponseYou've already chosen the best response.2ok but that would be that we need to square both sides right?

Best ResponseYou've already chosen the best response.2\[x^28=(8x)(8x) \] \[x^28=648x8x+x^2\] \[x^28=6416x+x^2\] oh I think I see how it will work now.

Best ResponseYou've already chosen the best response.2now try bringing all variables to the left and all numbers to the right

Best ResponseYou've already chosen the best response.2ok so now divide 16 from both sides

Best ResponseYou've already chosen the best response.2I was trying to get a step by step solution to see how the 9 happen but these sites... I swear they love making a profit off of people for the whole guide. yes! WE GOT IT!

Best ResponseYou've already chosen the best response.2whoops ._> I think we should've have \[(x8)^2=(\sqrt{x ^{2}8})^2\] \[(x8)(x8)=x^28\] \[x^216x+64=x^28\] allaaalalal and it should be x =9/2

Best ResponseYou've already chosen the best response.0lol so I'm having a bit of trouble checking it because its a fraction >.< I hate fractions

Best ResponseYou've already chosen the best response.2\[\frac{9}{2}8=\sqrt{(\frac{81}{4}) 8}\] then use lcd

Best ResponseYou've already chosen the best response.0Ok so I used a decimal instead and i got 9.25=8.25 so I think there is no solution but I'm not sure if I did the math right.

Best ResponseYou've already chosen the best response.2don't use decimals. It's a pain
