What two numbers multiply to -987 and add up to -26?

Here we answer the question: "What two numbers multiply to -987 and add up to -26?"

The answer to your question is:

-47 and 21

Below we illustrate and prove that -47 and 21 multiply to -987 and add up to -26:

-47 × 21 = -987
-47 + 21 = -26

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

x² - 26x - 987 = 0

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

(x - 47 ) (x + 21)

To summarize, since -47 and 21 multiply to -987 and add up -26, you know that the following is true:

x² - 26x - 987 = (x - 47 ) (x + 21)
