Sums and Products of Roots HL
On this page, we learn all about roots of polynomial equations and how to use the formulae for the sum of the roots and the product of the roots. For the polynomial equation of degree n \sum_{r=0}^{n}a_rx^r=0 , the sum of the roots = -\dfrac{a_{n-1}}{a_n} , the product of the roots = (-1)^n\dfrac{a_0}{a_n} Key Concepts On this page, you should learn about Essentials The following videos will help you understand all...
