What two numbers multiply to -896 and add up to 40?

Here we answer the question: "What two numbers multiply to -896 and add up to 40?"

The answer to your question is:

-16 and 56

Below we illustrate and prove that -16 and 56 multiply to -896 and add up to 40:

-16 × 56 = -896
-16 + 56 = 40

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

x² + 40x - 896 = 0

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

(x - 16 ) (x + 56)

To summarize, since -16 and 56 multiply to -896 and add up 40, you know that the following is true:

x² + 40x - 896 = (x - 16 ) (x + 56)
