What two numbers multiply to -910 and add up to -123?

Here we answer the question: "What two numbers multiply to -910 and add up to -123?"

The answer to your question is:

-130 and 7

Below we illustrate and prove that -130 and 7 multiply to -910 and add up to -123:

-130 × 7 = -910
-130 + 7 = -123

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

x² - 123x - 910 = 0

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

(x - 130 ) (x + 7)

To summarize, since -130 and 7 multiply to -910 and add up -123, you know that the following is true:

x² - 123x - 910 = (x - 130 ) (x + 7)
