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

The answer to your question is:

-7 and 94


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

-7 × 94 = -658
-7 + 94 = 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 - 7 ) (x + 94)

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

x2 + 87x - 658 = (x - 7 ) (x + 94)
