What two numbers multiply to -58 and add up to 57?

Here we answer the question: "What two numbers multiply to -58 and add up to 57?"

The answer to your question is:

-1 and 58

Below we illustrate and prove that -1 and 58 multiply to -58 and add up to 57:

-1 × 58 = -58
-1 + 58 = 57

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

x² + 57x - 58 = 0

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

(x - 1 ) (x + 58)

To summarize, since -1 and 58 multiply to -58 and add up 57, you know that the following is true:

x² + 57x - 58 = (x - 1 ) (x + 58)
