What two numbers multiply to -130 and add up to -21?

Here we answer the question: "What two numbers multiply to -130 and add up to -21?"

The answer to your question is:

-26 and 5

Below we illustrate and prove that -26 and 5 multiply to -130 and add up to -21:

-26 × 5 = -130
-26 + 5 = -21

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

x² - 21x - 130 = 0

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

(x - 26 ) (x + 5)

To summarize, since -26 and 5 multiply to -130 and add up -21, you know that the following is true:

x² - 21x - 130 = (x - 26 ) (x + 5)
