**Descartes' Rule Of Signs 2000clicks.com**

Question 1131290: How many complex, real, and rational roots does the following polynomial have: 2x^5-4x^4-4x^2+5 I think the number of complex roots would be 5, and the number of rational roots would be 4, but am confused about how to find the number of real roots.... YEAH .The square root of 4 is EITHER 2 or–2 The square root of any positive real number n is vn or—vn By the way,the symbol v denotes " THE POSITVE SQUARE ROOT OF" SO, THE SQUARE ROOTS OF any real positive nunber x is denoted by ±vx BUT the square...

**Determine the Number of Positive and Negative Real Zeros**

12/01/2005 · Now to find out the number of distinct real roots between a and b, you evaluate all of the polynomials f0, f1, f2, etc. at a and count the number of times the sign changes. Then you do the same at b and subtract the second number from the first. The result is the number of real roots between a and b. To get the total number of real roots, evaluate at -infinity and +infinity. Evaluating at... The DesCartes’ Rule of Signs will tell you the number of positive and negative real roots of a polynomial \(P\left( x \right)\) by looking at the sign changes of the terms of that polynomial.
