What two numbers multiply to -664 and add up to 75?

Here we answer the question: "What two numbers multiply to -664 and add up to 75?"

The answer to your question is:

-8 and 83

Below we illustrate and prove that -8 and 83 multiply to -664 and add up to 75:

-8 × 83 = -664
-8 + 83 = 75

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

x² + 75x - 664 = 0

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

(x - 8 ) (x + 83)

To summarize, since -8 and 83 multiply to -664 and add up 75, you know that the following is true:

x² + 75x - 664 = (x - 8 ) (x + 83)
