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

The answer to your question is:

1 and 2

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

1 × 2 = 2
1 + 2 = 3

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

x² + 3x + 2 = 0

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

(x + 1 ) (x + 2)

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

x² + 3x + 2 = (x + 1 ) (x + 2)
