What two numbers multiply to -660 and add up to 43?

Here we answer the question: "What two numbers multiply to -660 and add up to 43?"

The answer to your question is:

-12 and 55

Below we illustrate and prove that -12 and 55 multiply to -660 and add up to 43:

-12 × 55 = -660
-12 + 55 = 43

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

x² + 43x - 660 = 0

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

(x - 12 ) (x + 55)

To summarize, since -12 and 55 multiply to -660 and add up 43, you know that the following is true:

x² + 43x - 660 = (x - 12 ) (x + 55)
