What two numbers multiply to -756 and add up to 40?

Here we answer the question: "What two numbers multiply to -756 and add up to 40?"

The answer to your question is:

-14 and 54

Below we illustrate and prove that -14 and 54 multiply to -756 and add up to 40:

-14 × 54 = -756
-14 + 54 = 40

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

x² + 40x - 756 = 0

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

(x - 14 ) (x + 54)

To summarize, since -14 and 54 multiply to -756 and add up 40, you know that the following is true:

x² + 40x - 756 = (x - 14 ) (x + 54)
