What two numbers multiply to -390 and add up to 59?

Here we answer the question: "What two numbers multiply to -390 and add up to 59?"

The answer to your question is:

-6 and 65

Below we illustrate and prove that -6 and 65 multiply to -390 and add up to 59:

-6 × 65 = -390
-6 + 65 = 59

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

x² + 59x - 390 = 0

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

(x - 6 ) (x + 65)

To summarize, since -6 and 65 multiply to -390 and add up 59, you know that the following is true:

x² + 59x - 390 = (x - 6 ) (x + 65)
