What two numbers multiply to 351 and add up to 120?

Here we answer the question: "What two numbers multiply to 351 and add up to 120?"

The answer to your question is:

3 and 117

Below we illustrate and prove that 3 and 117 multiply to 351 and add up to 120:

3 × 117 = 351
3 + 117 = 120

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

x² + 120x + 351 = 0

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

(x + 3 ) (x + 117)

To summarize, since 3 and 117 multiply to 351 and add up 120, you know that the following is true:

x² + 120x + 351 = (x + 3 ) (x + 117)
