What two numbers multiply to -658 and add up to -87?

Here we answer the question: "What two numbers multiply to -658 and add up to -87?"

The answer to your question is:

-94 and 7

Below we illustrate and prove that -94 and 7 multiply to -658 and add up to -87:

-94 × 7 = -658
-94 + 7 = -87

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

x² - 87x - 658 = 0

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

(x - 94 ) (x + 7)

To summarize, since -94 and 7 multiply to -658 and add up -87, you know that the following is true:

x² - 87x - 658 = (x - 94 ) (x + 7)
