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:

-1 and 3

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

-1 × 3 = -3
-1 + 3 = 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 - 1 ) (x + 3)

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

x² + 2x - 3 = (x - 1 ) (x + 3)
