Hi!
Hi jacks;
Thanks bobym and bob bundy Now and So So the equation has no real Roots.
Hi;
Sorry, (7,7), not closed interval.
How did you get that? With Cauchy's bound I am getting it in [7,7]... since where c is a root.
hi jacks,
Hi; Substitute two endpoints of of ∞ and ∞ into x. You will get the 7 x 2 matrix Count the number of sign changes in the first column and subtract the number of sign changes in the second column. 3  3 = 0 There are no real roots!
Prove that the equation has no real roots.
