Sagot :


The answer to your question is -45 and 6 as shown here:

-45 x 6 = -270
-45 + 6 = -39

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

x2 - 39x - 270 = 0

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

(X - 45 ) (X + 6)

To summarize, since -45 and 6 multiply to -270 and add up -39, you know that the following is true:

x2 - 39x - 270 = (X - 45 ) (X + 6)
