What two numbers multiply to -445 and add up to 84?

Here we answer the question: "What two numbers multiply to -445 and add up to 84?"

The answer to your question is:

-5 and 89

Below we illustrate and prove that -5 and 89 multiply to -445 and add up to 84:

-5 × 89 = -445
-5 + 89 = 84

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

x² + 84x - 445 = 0

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

(x - 5 ) (x + 89)

To summarize, since -5 and 89 multiply to -445 and add up 84, you know that the following is true:

x² + 84x - 445 = (x - 5 ) (x + 89)
