OpenStudy (mathmath333):

is there any other information given such as a+b+c=0 ?

rishavraj (rishavraj):

rishavraj (rishavraj):

just a clue a^2 - b^2 + b^2 - c^2 + c^2 - a^2 = 0 proceed

rishavraj (rishavraj):

lol @mathmath333 lemme know if u wanna try more :P

OpenStudy (mathmath333):

yep

rishavraj (rishavraj):

yep for wht...???u got the solution or u wanna try more ?? :/

OpenStudy (mathmath333):

i gave up on that que

rishavraj (rishavraj):

this is kinda good too if \[x^2 + x + 1 = 0\] then evaluate \[x^3 + \frac{ 1 }{ x^3 }\]

rishavraj (rishavraj):

@mathmath333 hav a look...the solution given by @Vijeya3 once again good work http://prnt.sc/akkg3a

OpenStudy (mathmath333):

-2 ?

rishavraj (rishavraj):

hmmm really ....... ?????? lemme solve tht ,..... I dont think

OpenStudy (vijeya3):

No that is not -2

rishavraj (rishavraj):

\[(x + \frac{ 1 }{ x })^3 = x^3 + \frac{ 1 }{ x^3 } + 3(x + \frac{ 1 }{ x })\]

rishavraj (rishavraj):

@Vijeya3 bawli ho gayi hai tu kya .???? pehle bolti hai -2 -_- kuch pee rakhha hai tune
