Here, students are taught that if the signs are the same, that is good (i.e. positive) and if the signs are different, that is bad (i.e. negative). If multiplying or dividing more than two integers, encourage students to take the numbers two at a time and constantly use the rule.

Since P(-x) = has 0 variations in sign, P has 0 negative real zeros, and so by Descartes' Rule of Signs, a = 0 is a lower bound. alternating signs, therefore, a=0 is lower bound all positive. Therefore, b = 6 is an upper bound. 120. Find integers that are upper and lower bounds for the real roots of the equation .

Descartes’ Rule of Signs. We can use Descartes’s rule of signs to give us a bit more information about our polynomial. We will assume the p(x) is a polynomial with real coefficients and nonzero constant term. The rule follows:

Furthermore, Descartes rule of signs can be used to narrow down the total number of real and complex roots, but for the most part, graphic calculators minimize how often these skills are stressed in today's curriculum. Finally, though it's beyond the scope of these notes to prove it, all polynomials of degree n have exactly n roots total.
