9^2+(x/2)^2=x^2

anonymous · Answer

does (x/2)^2 = (x/4)?

turingtest · Answer

what happened to the earlier version of this Q ?
you should just bump it. Deleting and reposting is prohibited

turingtest · Answer

no, you need to square the x as well

anonymous · Answer

so..
x^2-(x^2/4)=81?

turingtest · Answer

yes

turingtest · Answer

now multiply both sides by 4 to get rid of the fraction, and combine like terms

turingtest · Answer

...or at least that's one way to do it :)

turingtest · Answer

whomever is typing please do $not$ provide the final answer; it will be deleted.

anonymous · Answer

$$x=\sqrt{108}?$$ok so i got..
$$4x ^{2}-x ^{2}=324$$
$$x ^{2}=108$$

turingtest · Answer

excellent :)

anonymous · Answer

hey TuringTest hmm i'm sorry, as i registered today. i was just trying to help finding solution but ok i will be more careful after today, thanks for warning me :)

turingtest · Answer

sorry to seem mean, but I am trying to elevate the level of this site
plus, as you may have noticed, that last person provided the wrong answer anyway
so the better policy is to teach, not answer

turingtest · Answer

@clark_boy understood, no problem :)

anonymous · Answer

yes exactly I understand you, you are right. thank you :)
