What two numbers multiply to 390 and add up to 133?

Here we answer the question: "What two numbers multiply to 390 and add up to 133?"

The answer to your question is:

3 and 130

Below we illustrate and prove that 3 and 130 multiply to 390 and add up to 133:

3 × 130 = 390
3 + 130 = 133

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

x² + 133x + 390 = 0

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

(x + 3 ) (x + 130)

To summarize, since 3 and 130 multiply to 390 and add up 133, you know that the following is true:

x² + 133x + 390 = (x + 3 ) (x + 130)
