What two numbers multiply to -3 and add up to -2?

Here we answer the question: "What two numbers multiply to -3 and add up to -2?"

The answer to your question is:

-3 and 1

Below we illustrate and prove that -3 and 1 multiply to -3 and add up to -2:

-3 × 1 = -3
-3 + 1 = -2

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

x² - 2x - 3 = 0

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

(x - 3 ) (x + 1)

To summarize, since -3 and 1 multiply to -3 and add up -2, you know that the following is true:

x² - 2x - 3 = (x - 3 ) (x + 1)
