okay then let u = x^2 ? hehe . thanks . kinda new here.
OpenStudy (shubhamsrg):
yep..seems you got it..
OpenStudy (shubhamsrg):
note that since degree of x is 5, you should get 5 roots of the eqn.
OpenStudy (anonymous):
now4 since its divided d ?
OpenStudy (shubhamsrg):
what ?

the root will be 4
btw thx
OpenStudy (shubhamsrg):
nopes./still there be 5 roots..
OpenStudy (shubhamsrg):
i assume you are missing out that x=0 is also a root..
OpenStudy (anonymous):
how to get x=0??
OpenStudy (shubhamsrg):
by bringing everything on LHS and factoring out x, what do you get ?
