What two numbers multiply to -99 and add up to -30?

Here we answer the question: "What two numbers multiply to -99 and add up to -30?"

The answer to your question is:

-33 and 3

Below we illustrate and prove that -33 and 3 multiply to -99 and add up to -30:

-33 × 3 = -99
-33 + 3 = -30

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

x² - 30x - 99 = 0

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

(x - 33 ) (x + 3)

To summarize, since -33 and 3 multiply to -99 and add up -30, you know that the following is true:

x² - 30x - 99 = (x - 33 ) (x + 3)
