What two numbers multiply to -787 and add up to 786?

Here we answer the question: "What two numbers multiply to -787 and add up to 786?"

The answer to your question is:

-1 and 787

Below we illustrate and prove that -1 and 787 multiply to -787 and add up to 786:

-1 × 787 = -787
-1 + 787 = 786

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

x² + 786x - 787 = 0

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

(x - 1 ) (x + 787)

To summarize, since -1 and 787 multiply to -787 and add up 786, you know that the following is true:

x² + 786x - 787 = (x - 1 ) (x + 787)
