What two numbers multiply to -748 and add up to 57?

Here we answer the question: "What two numbers multiply to -748 and add up to 57?"

The answer to your question is:

-11 and 68

Below we illustrate and prove that -11 and 68 multiply to -748 and add up to 57:

-11 × 68 = -748
-11 + 68 = 57

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

x² + 57x - 748 = 0

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

(x - 11 ) (x + 68)

To summarize, since -11 and 68 multiply to -748 and add up 57, you know that the following is true:

x² + 57x - 748 = (x - 11 ) (x + 68)
