Let `f(x)=a_(5)x^(5)+a_(4)x^(4)+a_(3)x^(3)+a_(2)x^(2)+a_(1)x, "where" a_(i),s` are real and f (x) = 0 has a positive root `alpha_(0).` Then `f^(prime)(x)=0` has a positive root `alpha_1` such that 0 < `alpha_1` < `alpha_0` `f^(prime)(x)=0` has at least two real roots `f^('')(x)=0` has at least one real root none of these
