If p is a constant and `f(x) =|(x^2,x^3,x^4),(2,3,6),(p,p^2,p^3)|` if `f'(x)=0` have roots `alpha,beta` , then (1) `alpha` and `beta` have opposite sign and equal magnitude at p=`root`(3) (2) At p=1 , f''(x)=0 represent an identity (3) at p=2 ,product of roots are unity (4) at p=-`(root 3)` product of roots are positive
