What two numbers multiply to -651 and add up to 650?

Here we answer the question: "What two numbers multiply to -651 and add up to 650?"

The answer to your question is:

-1 and 651

Below we illustrate and prove that -1 and 651 multiply to -651 and add up to 650:

-1 × 651 = -651
-1 + 651 = 650

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

x² + 650x - 651 = 0

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

(x - 1 ) (x + 651)

To summarize, since -1 and 651 multiply to -651 and add up 650, you know that the following is true:

x² + 650x - 651 = (x - 1 ) (x + 651)
