If x = -1 and x = 3 are the roots of a quadratic, what are the factors?

(x + 1) and (x - 3)

Step-by-step explanation:

Given x = h is a root of a polynomial then a factor is (x - h)

Given x = - 1 and x = 3 are roots of the quadratic , then the factors are

(x - (- 1) ) and (x - 3) , that is

(x + 1) and (x - 3)
