What two numbers multiply to -783 and add up to 258?

Here we answer the question: "What two numbers multiply to -783 and add up to 258?"

The answer to your question is:

-3 and 261

Below we illustrate and prove that -3 and 261 multiply to -783 and add up to 258:

-3 × 261 = -783
-3 + 261 = 258

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

x² + 258x - 783 = 0

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

(x - 3 ) (x + 261)

To summarize, since -3 and 261 multiply to -783 and add up 258, you know that the following is true:

x² + 258x - 783 = (x - 3 ) (x + 261)
