What two numbers multiply to -810 and add up to 3?

Here we answer the question: "What two numbers multiply to -810 and add up to 3?"

The answer to your question is:

-27 and 30

Below we illustrate and prove that -27 and 30 multiply to -810 and add up to 3:

-27 × 30 = -810
-27 + 30 = 3

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

x² + 3x - 810 = 0

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

(x - 27 ) (x + 30)

To summarize, since -27 and 30 multiply to -810 and add up 3, you know that the following is true:

x² + 3x - 810 = (x - 27 ) (x + 30)
