The solutions of a quadratic equation are 5 and -1. What is the factored form of a related quadratic function?

a) f(x) = (x + 5)(x - 1)
b) f(x) = (x + 5)(x + 1)
c) f(x) = (x - 5)(x - 5)
d) f(x) = (x - 5)(x + 1)

We should find  x= 5 and x= -1

A) f(x)= (x+ 5)(x- 1)  

x= -5 and x= 1

B) f(x)= (x+ 5)(x+ 1)

x= -5 and x= -1

C) f(x)= (x- 5)(x- 5)

x= 5 and x= 5

D) f(x)= (x- 5)(x+ 1)

x= 5 and x= -1
