WebJul 20, 2024 · As you have worked out, there is at least one root in each of the intervals ( 0, 1) and ( 1, 2). The number of positive roots as given by the rule of signs is zero or two, so there are exactly two positive roots. Applying the rule of signs to the polynomial with x replaced by x ( − x 5 + 5 x + 2) we see there is exactly one negative root. WebFind the Roots (Zeros) y=x^2-2x-3. Step 1. Set equal to . Step 2.

WebOct 23, 2024 · altavistard Answer: No complex roots; 3 real roots Step-by-step explanation: If a third order polynomial has any complex roots, then as a rule it has 1 real root and 2 complex roots. In this particular case, the polynomial has three real roots, as can be determined by graphing the function. The graph crosses the x-axis in 3 places. … WebThus, in order to determine the roots of polynomial p (x), we have to find the value of x for which p (x) = 0. Now, 5x + 1 = 0 x = -1/5 Hence, ‘-1/5’ is the root of the polynomial p (x). Questions and Solutions Example 1: Check whether -2 is a root of polynomial 3x3 + 5x2 + 6x + 4.
