need help

OpenStudy (rock_mit182):

\[3X^2 +3X <5X -1\]

OpenStudy (rock_mit182):

YEAH PLEASE Move all terms to one side of the inequality leaving zero on the other side.

OpenStudy (bonnieisflash1.0):

okay

OpenStudy (rock_mit182):

\[3x^2^-2x +1<0\]

OpenStudy (rock_mit182):

is it a complex solution ?

OpenStudy (rock_mit182):

@bonnieisflash1.0 ?

OpenStudy (bonnieisflash1.0):

sure

OpenStudy (bonnieisflash1.0):

but i can help

OpenStudy (rock_mit182):

i dont have a clue and i cant fail..

OpenStudy (bonnieisflash1.0):

what happen if you fail

OpenStudy (rock_mit182):

I could fail the whole test and I'm just starting :/

OpenStudy (bonnieisflash1.0):

oh

OpenStudy (rock_mit182):

I never thought it would be like this

OpenStudy (rock_mit182):

@inkyvoyd

OpenStudy (bonnieisflash1.0):

what do you think the answer is

OpenStudy (rock_mit182):

....answer...... <0

OpenStudy (rock_mit182):

it could be 1/3 (1 -sqrt2 i)

OpenStudy (bonnieisflash1.0):

go with your answer

OpenStudy (rock_mit182):

I think solving by quadratic formula we should take the negative part and therefore it would be less than 0

OpenStudy (bonnieisflash1.0):

if you are sure that is the answer

OpenStudy (bonnieisflash1.0):

bye

OpenStudy (rock_mit182):

But speaking of complex numbers its conjugate isnt always part of the solution, which means two solutions but i dont eve know if am i right..

OpenStudy (bonnieisflash1.0):

or you still need help

OpenStudy (rock_mit182):

I'm not sure cause is the first time i solve a problem like this

OpenStudy (rock_mit182):

I always work with real solutions..

OpenStudy (bonnieisflash1.0):

okay

OpenStudy (rock_mit182):

what do you think anyway, do you know how to figure this out ?

OpenStudy (rock_mit182):

ok bro thanks anyway,bye
