What two numbers multiply to -531 and add up to 530?

Here we answer the question: "What two numbers multiply to -531 and add up to 530?"

The answer to your question is:

-1 and 531

Below we illustrate and prove that -1 and 531 multiply to -531 and add up to 530:

-1 × 531 = -531
-1 + 531 = 530

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

x² + 530x - 531 = 0

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

(x - 1 ) (x + 531)

To summarize, since -1 and 531 multiply to -531 and add up 530, you know that the following is true:

x² + 530x - 531 = (x - 1 ) (x + 531)
