Direct link to sakshi190704's post For root(7x^2 + 15x) - 2x, Posted 2 years ago. A polynomial has one root that equals 4+17i. image/svg+xml. This is not a polynomial, since we have a radical in the first term. For example, look at the following roots: If x = -1/2, ( x - (-1/2)) is your factor, which you write as ( x + 1/2). How do you use those roots to find the factors of the polynomial? The factor theorem states that if x = c is a root, ( x - c) is a factor. Solution: Given, 2 + squareroot 3 is a polynomial root. saying it is we could write this as a Think about the definition of prime number. If so, what is its degree?
