What two numbers multiply to -91 and add up to -6?

Here we answer the question: "What two numbers multiply to -91 and add up to -6?"

The answer to your question is:

-13 and 7

Below we illustrate and prove that -13 and 7 multiply to -91 and add up to -6:

-13 × 7 = -91
-13 + 7 = -6

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

x² - 6x - 91 = 0

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

(x - 13 ) (x + 7)

To summarize, since -13 and 7 multiply to -91 and add up -6, you know that the following is true:

x² - 6x - 91 = (x - 13 ) (x + 7)
