WebFinding roots is looking at the factored form of the polynomial, where it is also factored into its complex/ imaginary parts, and finding how to make each binomial be 0. In a degree two polynomial you will ALWAYS be able to break it into two binomials. So it has two roots, both of which are 0, which means it has one ZERO which is 0. WebIf you are talking about roots for quadratic equations, you can just plug in the required numbers into the quadratic equation. If you are talking about n-order equations, you can either factor them out to give you the roots or graph them to show you the roots.
