What two numbers multiply to 770 and add up to 387?

Here we answer the question: "What two numbers multiply to 770 and add up to 387?"

The answer to your question is:

2 and 385

Below we illustrate and prove that 2 and 385 multiply to 770 and add up to 387:

2 × 385 = 770
2 + 385 = 387

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

x² + 387x + 770 = 0

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

(x + 2 ) (x + 385)

To summarize, since 2 and 385 multiply to 770 and add up 387, you know that the following is true:

x² + 387x + 770 = (x + 2 ) (x + 385)
