WebThe conjugate root theorem tells us that nonreal roots of polynomials with real coefficients occur in complex conjugate pairs. As a result of these two theorems, we can categorize the nature of the roots of polynomials. We can use the conjugate root to help us solve cubic and quartic equations with real coefficients. Web1.1 Polynomial equations and their roots If, for a polynomial P(x), P(k) = 0 then we can say 1. x = k is a root of the equation P(x)=0. 2. x = k is a zero of P(x). 3. k is an x-intercept of the graph of P(x). 1.1.1 Zeros of the quadratic polynomial The quadratic polynomial equation Q(x)=ax2 +bx+c = 0 has two roots that may be: 1. real (rational ...
