What two numbers multiply to -990 and add up to 3?

Here we answer the question: "What two numbers multiply to -990 and add up to 3?"

The answer to your question is:

-30 and 33

Below we illustrate and prove that -30 and 33 multiply to -990 and add up to 3:

-30 × 33 = -990
-30 + 33 = 3

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

x² + 3x - 990 = 0

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

(x - 30 ) (x + 33)

To summarize, since -30 and 33 multiply to -990 and add up 3, you know that the following is true:

x² + 3x - 990 = (x - 30 ) (x + 33)
