What two numbers multiply to -910 and add up to 57?

Here we answer the question: "What two numbers multiply to -910 and add up to 57?"

The answer to your question is:

-13 and 70

Below we illustrate and prove that -13 and 70 multiply to -910 and add up to 57:

-13 × 70 = -910
-13 + 70 = 57

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

x² + 57x - 910 = 0

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

(x - 13 ) (x + 70)

To summarize, since -13 and 70 multiply to -910 and add up 57, you know that the following is true:

x² + 57x - 910 = (x - 13 ) (x + 70)
