What two numbers multiply to -66 and add up to -31?

Here we answer the question: "What two numbers multiply to -66 and add up to -31?"

The answer to your question is:

-33 and 2

Below we illustrate and prove that -33 and 2 multiply to -66 and add up to -31:

-33 × 2 = -66
-33 + 2 = -31

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

x² - 31x - 66 = 0

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

(x - 33 ) (x + 2)

To summarize, since -33 and 2 multiply to -66 and add up -31, you know that the following is true:

x² - 31x - 66 = (x - 33 ) (x + 2)
