What two numbers multiply to -528 and add up to -128?

Here we answer the question: "What two numbers multiply to -528 and add up to -128?"

The answer to your question is:

-132 and 4

Below we illustrate and prove that -132 and 4 multiply to -528 and add up to -128:

-132 × 4 = -528
-132 + 4 = -128

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

x² - 128x - 528 = 0

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

(x - 132 ) (x + 4)

To summarize, since -132 and 4 multiply to -528 and add up -128, you know that the following is true:

x² - 128x - 528 = (x - 132 ) (x + 4)
