What two numbers multiply to -525 and add up to 4?

Here we answer the question: "What two numbers multiply to -525 and add up to 4?"

The answer to your question is:

-21 and 25

Below we illustrate and prove that -21 and 25 multiply to -525 and add up to 4:

-21 × 25 = -525
-21 + 25 = 4

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

x² + 4x - 525 = 0

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

(x - 21 ) (x + 25)

To summarize, since -21 and 25 multiply to -525 and add up 4, you know that the following is true:

x² + 4x - 525 = (x - 21 ) (x + 25)
