Hi, i was wondering how you would solve the equation

30+1144*r^4-832*r^2=0, 

exactly in maple.

Using the command

fsolve(30+1144*r^4-832*r^2);

-0.8301954535, -0.1950595709, 0.1950595709, 0.8301954535

Also, if possible how would you get maple to find the two exact positive solutions.

 

Thanks
