Sagot :

Answer:

1 and 12

Step-by-step explanation:

as proven here:

1 x 12 = 12

1 + (12) = 13

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x2 + 13x + 12 = 0

If so, the solution to factor the quadratic equation above is:

(X + 1 ) (X + 12)

To summarize, since 1 and 12 multiply to 12 and add up 13, you know that the following is true:

x2 + 13x + 12 = (X + 1 ) (X + 12)
