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:

-10 and 97

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

-10 × 97 = -970
-10 + 97 = 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 - 10 ) (x + 97)

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

x² + 87x - 970 = (x - 10 ) (x + 97)
