What two numbers multiply to -240 and add up to 43?

Here we answer the question: "What two numbers multiply to -240 and add up to 43?"

The answer to your question is:

-5 and 48

Below we illustrate and prove that -5 and 48 multiply to -240 and add up to 43:

-5 × 48 = -240
-5 + 48 = 43

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

x² + 43x - 240 = 0

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

(x - 5 ) (x + 48)

To summarize, since -5 and 48 multiply to -240 and add up 43, you know that the following is true:

x² + 43x - 240 = (x - 5 ) (x + 48)
