solve for x?

lgbasallote Group TitleBest ResponseYou've already chosen the best response.0
here's my thought let x  1 = a therefore a +1 = x 2a^3 = a + 1 + 1 2a^3 = a + 2 2a^3  a  2 = 0 does that give you any ideas?

Try doing a little of testing possible rational zeros for what you have

lol im only in alg/trig in high schooll.. loll wut is that?

myininaya Group TitleBest ResponseYou've already chosen the best response.2
oh wait i think i made a mistake anyways... let me try again but yeah that is what i would do test to see if any possible rational zeros work

well im takling the algebra2/trig course right now at summer school

synthetic division and looking at possible rational zeros are in algebra

And is your equation written correctly?

louis413 Group TitleBest ResponseYou've already chosen the best response.0
yes can it be solved like 2(x1)^2(x1)1(X1)=0

I can only see to find a real approximation by looking at the graph and seeing where it crosses the xaxis

would you like to go for a trignometric solution? might seem complicated but is easy.. involves inverse function just a bit..and sin 3x etc formullas ?
 2 years ago

shubhamsrg Group TitleBest ResponseYou've already chosen the best response.3
well.. in 2a^3  a  2 = 0 let a = m sin y => 2m^3 sin^3 y  msin y 2 =0 multiplying both sides by (2/m^3) => 4sin^3 y + 2sin y/(m^2) + 4/(m^3) =0 our aim is to convert this in the form of 4sin^3 y + 3 siny which will convert it into sin 3y and simplify things we have to chose a particular value of m for that purpose in our case 2/m^2 = 3 or m = sqrt(3/2) and sqrt(3/2) thus we have these 2 eqns : 4sin^3 y + 3sin y + 8sqrt(2)/(3sqrt(3)) = 0 and 4sin^3 y + 3sin y  8sqrt(2)/(3sqrt(3)) = 0 => sin 3y =  8sqrt(2)/(3sqrt(3)) and =>sin 3y = 8sqrt(2)/(3sqrt(3)) now using any scientific calculator, we may find value of y,then a(=msin y) and then finally x(=a+1)
