What two numbers multiply to -475 and add up to 90?

Here we answer the question: "What two numbers multiply to -475 and add up to 90?"

The answer to your question is:

-5 and 95

Below we illustrate and prove that -5 and 95 multiply to -475 and add up to 90:

-5 × 95 = -475
-5 + 95 = 90

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

x² + 90x - 475 = 0

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

(x - 5 ) (x + 95)

To summarize, since -5 and 95 multiply to -475 and add up 90, you know that the following is true:

x² + 90x - 475 = (x - 5 ) (x + 95)
