What two numbers multiply to -90 and add up to -27?

Here we answer the question: "What two numbers multiply to -90 and add up to -27?"

The answer to your question is:

-30 and 3

Below we illustrate and prove that -30 and 3 multiply to -90 and add up to -27:

-30 × 3 = -90
-30 + 3 = -27

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

x² - 27x - 90 = 0

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

(x - 30 ) (x + 3)

To summarize, since -30 and 3 multiply to -90 and add up -27, you know that the following is true:

x² - 27x - 90 = (x - 30 ) (x + 3)
