What two numbers multiply to -676 and add up to 675?

Here we answer the question: "What two numbers multiply to -676 and add up to 675?"

The answer to your question is:

-1 and 676

Below we illustrate and prove that -1 and 676 multiply to -676 and add up to 675:

-1 × 676 = -676
-1 + 676 = 675

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

x² + 675x - 676 = 0

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

(x - 1 ) (x + 676)

To summarize, since -1 and 676 multiply to -676 and add up 675, you know that the following is true:

x² + 675x - 676 = (x - 1 ) (x + 676)
