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:

3 and 141

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

3 × 141 = 423
3 + 141 = 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 + 3 ) (x + 141)

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

x² + 144x + 423 = (x + 3 ) (x + 141)
