What two numbers multiply to 780 and add up to 199?

Here we answer the question: "What two numbers multiply to 780 and add up to 199?"

The answer to your question is:

4 and 195

Below we illustrate and prove that 4 and 195 multiply to 780 and add up to 199:

4 × 195 = 780
4 + 195 = 199

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

x² + 199x + 780 = 0

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

(x + 4 ) (x + 195)

To summarize, since 4 and 195 multiply to 780 and add up 199, you know that the following is true:

x² + 199x + 780 = (x + 4 ) (x + 195)
