What two numbers multiply to -928 and add up to 42?

Here we answer the question: "What two numbers multiply to -928 and add up to 42?"

The answer to your question is:

-16 and 58

Below we illustrate and prove that -16 and 58 multiply to -928 and add up to 42:

-16 × 58 = -928
-16 + 58 = 42

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

x² + 42x - 928 = 0

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

(x - 16 ) (x + 58)

To summarize, since -16 and 58 multiply to -928 and add up 42, you know that the following is true:

x² + 42x - 928 = (x - 16 ) (x + 58)
