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:

-66 and 11

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

-66 × 11 = -726
-66 + 11 = -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 - 66 ) (x + 11)

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

x² - 55x - 726 = (x - 66 ) (x + 11)
