What two numbers multiply to -920 and add up to 17?




Here we answer the question: "What two numbers multiply to -920 and add up to 17?"

The answer to your question is:

-23 and 40


Below we illustrate and prove that -23 and 40 multiply to -920 and add up to 17:

-23 × 40 = -920
-23 + 40 = 17

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

x2 + 17x - 920 = 0

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

(x - 23 ) (x + 40)

To summarize, since -23 and 40 multiply to -920 and add up 17, you know that the following is true:

x2 + 17x - 920 = (x - 23 ) (x + 40)
