What two numbers multiply to -651 and add up to 86?

Here we answer the question: "What two numbers multiply to -651 and add up to 86?"

The answer to your question is:

-7 and 93

Below we illustrate and prove that -7 and 93 multiply to -651 and add up to 86:

-7 × 93 = -651
-7 + 93 = 86

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

x² + 86x - 651 = 0

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

(x - 7 ) (x + 93)

To summarize, since -7 and 93 multiply to -651 and add up 86, you know that the following is true:

x² + 86x - 651 = (x - 7 ) (x + 93)
