What two numbers multiply to -266 and add up to 31?

Here we answer the question: "What two numbers multiply to -266 and add up to 31?"

The answer to your question is:

-7 and 38

Below we illustrate and prove that -7 and 38 multiply to -266 and add up to 31:

-7 × 38 = -266
-7 + 38 = 31

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

x² + 31x - 266 = 0

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

(x - 7 ) (x + 38)

To summarize, since -7 and 38 multiply to -266 and add up 31, you know that the following is true:

x² + 31x - 266 = (x - 7 ) (x + 38)
