Descartes' Rule of Signs | Definition, Examples & Uses - Video | Study.com

Descartes' Rule of Signs Use Descartes' Rule of Signs to determine how many positive and how many negative real zeros the polynomial can have. Then determine the possible total number of real zeros. P(x)=x^3-x^2-x-3 | Numerade

Use Descartes's Rule of Signs to determine the possible number of positive and negative real zeros of f(x)=x^5-x^4 x^3-x^2 x-8 using a graphing utility to graph f | Numerade

SOLVED:For each polynomial (a) use Descartes' rule of signs to determine the possible combinations of positive real zeros and negative real zeros; (b) use the rational zero test to determine possible rational zeros; (c) test for rational zeros; and (d) factor as a product of linear and/or irreducible quadratic factors. P(x)=4 x^4-8 x^3 7 x^2 30 x 50
