Display more than just one root

[conrad8]

Hi,

I have an equation which has one variable Y2 but two instances of it, ignore Y1 as have numbers to plug in for those.

Basically I know all variables except Y2



Anyhow - when I use the HP Prime SOLVE APP to find a solution
it does solve the the Y2 variable but only puts out ONE solution of the the 3
I know that exist.. my friend sitting next to me has a Ti Nspire and his has 3 root solutions.... and we need all 3 to move ahead with these conjugate problems... driving me mad!!!!

how do I get the HP prime to list ALL the solutions.. I've managed to play around with the plot range and got the a valid different one solution but thats trial and error...

Please help if you can.. Thanks

Here is a quick image link from the internet of a random hp prime solve page but with multivariable being solved... can this type of page display the two positive and one negative values of Y??????


Heres a link to the kind of equations Im having to solve (scroll down to Conjugate Depths in a Rectangular Channel):
