What two numbers multiply to -726 and add up to 115?

Here we answer the question: "What two numbers multiply to -726 and add up to 115?"

The answer to your question is:

-6 and 121

Below we illustrate and prove that -6 and 121 multiply to -726 and add up to 115:

-6 × 121 = -726
-6 + 121 = 115

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

x² + 115x - 726 = 0

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

(x - 6 ) (x + 121)

To summarize, since -6 and 121 multiply to -726 and add up 115, you know that the following is true:

x² + 115x - 726 = (x - 6 ) (x + 121)
