WebWhat is a root function? A root is a value for which the function equals zero. The roots are the points where the function intercept with the x-axis; What are complex roots? … WebBecause this polynomial has real coefficients, that means that the complex conjugate -i is also a root. So we can factor out (x+i) (x-i)=x²+1 with synthetic division. This gives us (x²+2x+1) (x²+1). Now we can use the quadratic formula to find the roots of x²+2x+1. We get [-2±√ (4-4)]/2= -2/2= -1. WebFactorization of any degree of polynomial begins the same way. You start by taking integers on the number line and place x, the variable under question equal to those values. Once you find 3 values of x, you have the solution roots.
