What two numbers multiply to -396 and add up to 60?

Here we answer the question: "What two numbers multiply to -396 and add up to 60?"

The answer to your question is:

-6 and 66

Below we illustrate and prove that -6 and 66 multiply to -396 and add up to 60:

-6 × 66 = -396
-6 + 66 = 60

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

x² + 60x - 396 = 0

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

(x - 6 ) (x + 66)

To summarize, since -6 and 66 multiply to -396 and add up 60, you know that the following is true:

x² + 60x - 396 = (x - 6 ) (x + 66)
