What two numbers multiply to 396 and add up to 103?

Here we answer the question: "What two numbers multiply to 396 and add up to 103?"

The answer to your question is:

4 and 99

Below we illustrate and prove that 4 and 99 multiply to 396 and add up to 103:

4 × 99 = 396
4 + 99 = 103

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

x² + 103x + 396 = 0

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

(x + 4 ) (x + 99)

To summarize, since 4 and 99 multiply to 396 and add up 103, you know that the following is true:

x² + 103x + 396 = (x + 4 ) (x + 99)
