What two numbers multiply to -528 and add up to 58?

Here we answer the question: "What two numbers multiply to -528 and add up to 58?"

The answer to your question is:

-8 and 66

Below we illustrate and prove that -8 and 66 multiply to -528 and add up to 58:

-8 × 66 = -528
-8 + 66 = 58

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

x² + 58x - 528 = 0

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

(x - 8 ) (x + 66)

To summarize, since -8 and 66 multiply to -528 and add up 58, you know that the following is true:

x² + 58x - 528 = (x - 8 ) (x + 66)
