WebExample 1. An example of a polynomial (with degree 3) is: p(x) = 4x 3 − 3x 2 − 25x − 6. The factors of this polynomial are: (x − 3), (4x + 1), and (x + 2) Note there are 3 factors for a degree 3 polynomial. When we multiply those 3 terms in brackets, we'll end up with the polynomial p(x). WebWell you could probably do this in your head, or we could do it systematically as well. Subtract 1 from both sides, you get 2x equals negative 1. Divide both sides by 2, you get x is equal to negative 1/2. So when x equals negative 1/2-- or one way to think about it, p of negative 1/2 is 0. So p of negative 1/2 is 0. how to get to your library in steam
