What two numbers multiply to 280 and add up to -43?

Here we answer the question: "What two numbers multiply to 280 and add up to -43?"

The answer to your question is:

-35 and -8

Below we illustrate and prove that -35 and -8 multiply to 280 and add up to -43:

-35 × -8 = 280
-35 + -8 = -43

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

x² - 43x + 280 = 0

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

(x - 35 ) (x - 8)

To summarize, since -35 and -8 multiply to 280 and add up -43, you know that the following is true:

x² - 43x + 280 = (x - 35 ) (x - 8)
