What two numbers multiply to -630 and add up to -121?

Here we answer the question: "What two numbers multiply to -630 and add up to -121?"

The answer to your question is:

-126 and 5

Below we illustrate and prove that -126 and 5 multiply to -630 and add up to -121:

-126 × 5 = -630
-126 + 5 = -121

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

x² - 121x - 630 = 0

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

(x - 126 ) (x + 5)

To summarize, since -126 and 5 multiply to -630 and add up -121, you know that the following is true:

x² - 121x - 630 = (x - 126 ) (x + 5)
