What is the factored form of x2 − 4x − 5? (x + 5)(x − 1) (x + 5)(x + 1) (x − 5)(x − 1) (x − 5)(x + 1)

For this case we have the following polynomial:
 x2 - 4x - 5
 Factoring we must arrive at a polynomial of the form:
 (x-a) * (x-b)
 We have then:
 (x-5) * (x + 1)
 
 the factored form of x2 - 4x - 5 is:
 (x-5) * (x + 1)
