What two numbers multiply to -673 and add up to 672?

Here we answer the question: "What two numbers multiply to -673 and add up to 672?"

The answer to your question is:

-1 and 673

Below we illustrate and prove that -1 and 673 multiply to -673 and add up to 672:

-1 × 673 = -673
-1 + 673 = 672

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

x² + 672x - 673 = 0

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

(x - 1 ) (x + 673)

To summarize, since -1 and 673 multiply to -673 and add up 672, you know that the following is true:

x² + 672x - 673 = (x - 1 ) (x + 673)
