What two numbers multiply to 384 and add up to 131?

Here we answer the question: "What two numbers multiply to 384 and add up to 131?"

The answer to your question is:

3 and 128

Below we illustrate and prove that 3 and 128 multiply to 384 and add up to 131:

3 × 128 = 384
3 + 128 = 131

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

x² + 131x + 384 = 0

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

(x + 3 ) (x + 128)

To summarize, since 3 and 128 multiply to 384 and add up 131, you know that the following is true:

x² + 131x + 384 = (x + 3 ) (x + 128)
