What two numbers multiply to -260 and add up to 7?

Here we answer the question: "What two numbers multiply to -260 and add up to 7?"

The answer to your question is:

-13 and 20

Below we illustrate and prove that -13 and 20 multiply to -260 and add up to 7:

-13 × 20 = -260
-13 + 20 = 7

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

x² + 7x - 260 = 0

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

(x - 13 ) (x + 20)

To summarize, since -13 and 20 multiply to -260 and add up 7, you know that the following is true:

x² + 7x - 260 = (x - 13 ) (x + 20)
