WebIt is not saying that the roots = 0. A root or a zero of a polynomial are the value (s) of X that cause the polynomial to = 0 (or make Y=0). It is an X-intercept. The root is the X-value, and zero is the Y-value. It is not saying that imaginary roots = 0. 2 comments ( 6 votes) Keerthana Revinipati 5 years ago How do you graph polynomials? • WebUse Descartes' Rule of Signs to find the number of real roots of: f (x) = x5 + x4 + 4x3 + 3x2 + x + 1 I look first at f (x): f ( x) = +x5 + x4 + 4 x3 + 3 x2 + x + 1 There are no sign changes, so there are zero positive roots. Now I look at f (−x): f (− x) = (− x) 5 + (− x) 4 + 4 (− x) 3 + 3 (− x) 2 + (− x) + 1 = −x5 + x4 − 4 x3 + 3 x2 − x + 1 high hold matte finishWebYes, square roots can create 2 answers -- the positive (principal) root and the negative root. When you are working with square roots in an expression, you need to know which value you are expected to use. The default is the principal root. We only use the negative root when there is a minus in front of the radical. For example: 8 + sqrt (9) = 11 how i ruined my whole life in college
