What two numbers multiply to -279 and add up to -90?

Here we answer the question: "What two numbers multiply to -279 and add up to -90?"

The answer to your question is:

-93 and 3

Below we illustrate and prove that -93 and 3 multiply to -279 and add up to -90:

-93 × 3 = -279
-93 + 3 = -90

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

x² - 90x - 279 = 0

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

(x - 93 ) (x + 3)

To summarize, since -93 and 3 multiply to -279 and add up -90, you know that the following is true:

x² - 90x - 279 = (x - 93 ) (x + 3)
