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:

-12 and 75

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

-12 × 75 = -900
-12 + 75 = 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 - 12 ) (x + 75)

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

x² + 63x - 900 = (x - 12 ) (x + 75)
