Finding zeros of polynomials practice

WebJul 12, 2024 · There are two results that can help us identify where the zeros of a polynomial are. The first gives us an interval on which all the real zeros of a polynomial can be found. let M be the largest of the coefficients in absolute value. Then all the real zeros of f(x) lie in the interval. Let f(x) = 2x4 + 4x3 − x2 − 6x − 3. Webor factor to find the remaining zeros. Example 2: Find all real zeros of the polynomial P(x) = 2x4 + x3 – 6x2 – 7x – 2. Solution: Step 1: First list all possible rational zeros using the Rational Zeros . Theorem. For the rational number . p q. to be a zero, p. must be a . factor of . a. 0 = 2 and . q. must be a factor of . a. n = 2. Thus ...
