What two numbers multiply to -621 and add up to 60?

Here we answer the question: "What two numbers multiply to -621 and add up to 60?"

The answer to your question is:

-9 and 69

Below we illustrate and prove that -9 and 69 multiply to -621 and add up to 60:

-9 × 69 = -621
-9 + 69 = 60

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

x² + 60x - 621 = 0

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

(x - 9 ) (x + 69)

To summarize, since -9 and 69 multiply to -621 and add up 60, you know that the following is true:

x² + 60x - 621 = (x - 9 ) (x + 69)
