Hello, my name is Carlos. I had a question on my regents that I was very confused about. Please if you know how to answer this question may you please answer it. Thank you and here is the question:

What are the roots of the equation x squared - 7x + 6 =0?
A) 1 and 7
B) -1 and 7
C) -1 and -6
D) 1 and 6

What are the roots of the equation x squared - 7x + 6 =0?
A) 1 and 7
B) -1 and 7
C) -1 and -6
D) 1 and 6

x^2 - 7x + 6 = 0 ; factor to get: (x - 6)(x - 1) = 0

Well I do understand how to factor (x - 6)(x - 1) which i well get x^2 - 7x + 6
what i want to know what is the answer from all four of the multiple choices, it is asking what are the roots of the equation x^2 - 7x + 6 =0? and the roots are one of the multiple choice answers but which one is it?

(x - 6)(x - 1) = 0 means that x - 6 = 0 and/or x - 1 = 0: so x = 6 or x = 1 ; got that?
