Here we answer the question: "What two numbers multiply to 3 and add up to -4?"

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 -4:

-3 × -1 = 3
-3 + -1 = -4

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

x² - 4x + 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 -4, you know that the following is true:

x² - 4x + 3 = (x - 3 ) (x - 1)
