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:

-7 and 130

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

-7 × 130 = -910
-7 + 130 = 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 - 7 ) (x + 130)

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

x² + 123x - 910 = (x - 7 ) (x + 130)
