What two numbers multiply to 120 and add up to -43?

Here we answer the question: "What two numbers multiply to 120 and add up to -43?"

The answer to your question is:

-40 and -3

Below we illustrate and prove that -40 and -3 multiply to 120 and add up to -43:

-40 × -3 = 120
-40 + -3 = -43

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

x² - 43x + 120 = 0

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

(x - 40 ) (x - 3)

To summarize, since -40 and -3 multiply to 120 and add up -43, you know that the following is true:

x² - 43x + 120 = (x - 40 ) (x - 3)
