Polynomials: Sums and Products of Roots

WebThe Fundamental Theorem of Algebra ultimately says that the degree of the polynomial, n, is how many roots the polynomial will have as long as you are counting complex numbers (which we are). That means that this polynomial will have 3 roots, whether complex or not. Ask Question Download Step 5: Use the Rational Root Theorem... WebThere is no imaginary root. Sometimes, roots turn out to be the same (see discussion above on "Zeroes & Multiplicity"). That is what is happening in this equation. So, the equation degrades to having only 2 roots. If you factor the polynomial, you get factors of: -X (X - 2) (X - 2). You can see, 2 of the factors are identical. broward low maintenance condo
