What two numbers multiply to 780 and add up to -263?

Here we answer the question: "What two numbers multiply to 780 and add up to -263?"

The answer to your question is:

-260 and -3

Below we illustrate and prove that -260 and -3 multiply to 780 and add up to -263:

-260 × -3 = 780
-260 + -3 = -263

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

x² - 263x + 780 = 0

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

(x - 260 ) (x - 3)

To summarize, since -260 and -3 multiply to 780 and add up -263, you know that the following is true:

x² - 263x + 780 = (x - 260 ) (x - 3)
