What two numbers multiply to 408 and add up to 106?

Here we answer the question: "What two numbers multiply to 408 and add up to 106?"

The answer to your question is:

4 and 102

Below we illustrate and prove that 4 and 102 multiply to 408 and add up to 106:

4 × 102 = 408
4 + 102 = 106

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

x² + 106x + 408 = 0

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

(x + 4 ) (x + 102)

To summarize, since 4 and 102 multiply to 408 and add up 106, you know that the following is true:

x² + 106x + 408 = (x + 4 ) (x + 102)
