What two numbers multiply to -969 and add up to 40?

Here we answer the question: "What two numbers multiply to -969 and add up to 40?"

The answer to your question is:

-17 and 57

Below we illustrate and prove that -17 and 57 multiply to -969 and add up to 40:

-17 × 57 = -969
-17 + 57 = 40

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

x² + 40x - 969 = 0

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

(x - 17 ) (x + 57)

To summarize, since -17 and 57 multiply to -969 and add up 40, you know that the following is true:

x² + 40x - 969 = (x - 17 ) (x + 57)
