What two numbers multiply to -900 and add up to -63?

Here we answer the question: "What two numbers multiply to -900 and add up to -63?"

The answer to your question is:

-75 and 12

Below we illustrate and prove that -75 and 12 multiply to -900 and add up to -63:

-75 × 12 = -900
-75 + 12 = -63

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

x² - 63x - 900 = 0

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

(x - 75 ) (x + 12)

To summarize, since -75 and 12 multiply to -900 and add up -63, you know that the following is true:

x² - 63x - 900 = (x - 75 ) (x + 12)
