What two numbers multiply to 423 and add up to -144?

Here we answer the question: "What two numbers multiply to 423 and add up to -144?"

The answer to your question is:

-141 and -3

Below we illustrate and prove that -141 and -3 multiply to 423 and add up to -144:

-141 × -3 = 423
-141 + -3 = -144

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

x² - 144x + 423 = 0

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

(x - 141 ) (x - 3)

To summarize, since -141 and -3 multiply to 423 and add up -144, you know that the following is true:

x² - 144x + 423 = (x - 141 ) (x - 3)
