What two numbers multiply to -286 and add up to 9?

Here we answer the question: "What two numbers multiply to -286 and add up to 9?"

The answer to your question is:

-13 and 22

Below we illustrate and prove that -13 and 22 multiply to -286 and add up to 9:

-13 × 22 = -286
-13 + 22 = 9

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

x² + 9x - 286 = 0

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

(x - 13 ) (x + 22)

To summarize, since -13 and 22 multiply to -286 and add up 9, you know that the following is true:

x² + 9x - 286 = (x - 13 ) (x + 22)
