What two numbers multiply to -528 and add up to 527?

Here we answer the question: "What two numbers multiply to -528 and add up to 527?"

The answer to your question is:

-1 and 528

Below we illustrate and prove that -1 and 528 multiply to -528 and add up to 527:

-1 × 528 = -528
-1 + 528 = 527

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

x² + 527x - 528 = 0

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

(x - 1 ) (x + 528)

To summarize, since -1 and 528 multiply to -528 and add up 527, you know that the following is true:

x² + 527x - 528 = (x - 1 ) (x + 528)
