What two numbers multiply to -970 and add up to -87?

Here we answer the question: "What two numbers multiply to -970 and add up to -87?"

The answer to your question is:

-97 and 10

Below we illustrate and prove that -97 and 10 multiply to -970 and add up to -87:

-97 × 10 = -970
-97 + 10 = -87

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

x² - 87x - 970 = 0

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

(x - 97 ) (x + 10)

To summarize, since -97 and 10 multiply to -970 and add up -87, you know that the following is true:

x² - 87x - 970 = (x - 97 ) (x + 10)
