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)

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %

is only a line? i think so
