What two numbers multiply to -4 and add up to -3?

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

The answer to your question is:

-4 and 1

Below we illustrate and prove that -4 and 1 multiply to -4 and add up to -3:

-4 × 1 = -4
-4 + 1 = -3

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

x² - 3x - 4 = 0

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

(x - 4 ) (x + 1)

To summarize, since -4 and 1 multiply to -4 and add up -3, you know that the following is true:

x² - 3x - 4 = (x - 4 ) (x + 1)
