Here we answer the question: "What two numbers multiply to -748 and add up to 747?"

The answer to your question is:

-1 and 748

Below we illustrate and prove that -1 and 748 multiply to -748 and add up to 747:

-1 × 748 = -748
-1 + 748 = 747

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

x² + 747x - 748 = 0

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

(x - 1 ) (x + 748)

To summarize, since -1 and 748 multiply to -748 and add up 747, you know that the following is true:

x² + 747x - 748 = (x - 1 ) (x + 748)
