What's Next?

Descartes' Rule of Signs is a theorem that helps determine the number of positive and negative real roots of a polynomial equation. In simpler terms, it allows you to predict how many real solutions (x-values) a quadratic equation will have. To apply the rule, you count the signs of the coefficients in the polynomial. For a 2nd-degree polynomial equation of the form ax^2 + bx + c = 0, you count the number of sign changes between consecutive coefficients (a, b, c) from left to right. This count usually matches the number of positive roots. For negative roots, you can use a modified version of the rule that involves factorizing coefficients.

To get started with the rule, see a 2nd-degree polynomial equation with a, b, and c coefficients. For instance, examine the equation -x^2 + 5x - 2 = 0. To count the number of sign changes, follow these steps:
