What two numbers multiply to -530 and add up to 263?

Here we answer the question: "What two numbers multiply to -530 and add up to 263?"

The answer to your question is:

-2 and 265

Below we illustrate and prove that -2 and 265 multiply to -530 and add up to 263:

-2 × 265 = -530
-2 + 265 = 263

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

x² + 263x - 530 = 0

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

(x - 2 ) (x + 265)

To summarize, since -2 and 265 multiply to -530 and add up 263, you know that the following is true:

x² + 263x - 530 = (x - 2 ) (x + 265)
