What two numbers multiply to -788 and add up to 787?

Here we answer the question: "What two numbers multiply to -788 and add up to 787?"

The answer to your question is:

-1 and 788

Below we illustrate and prove that -1 and 788 multiply to -788 and add up to 787:

-1 × 788 = -788
-1 + 788 = 787

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

x² + 787x - 788 = 0

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

(x - 1 ) (x + 788)

To summarize, since -1 and 788 multiply to -788 and add up 787, you know that the following is true:

x² + 787x - 788 = (x - 1 ) (x + 788)
