What two numbers multiply to -726 and add up to 55?

Here we answer the question: "What two numbers multiply to -726 and add up to 55?"

The answer to your question is:

-11 and 66

Below we illustrate and prove that -11 and 66 multiply to -726 and add up to 55:

-11 × 66 = -726
-11 + 66 = 55

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

x² + 55x - 726 = 0

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

(x - 11 ) (x + 66)

To summarize, since -11 and 66 multiply to -726 and add up 55, you know that the following is true:

x² + 55x - 726 = (x - 11 ) (x + 66)
