What two numbers multiply to -266 and add up to 265?

Here we answer the question: "What two numbers multiply to -266 and add up to 265?"

The answer to your question is:

-1 and 266

Below we illustrate and prove that -1 and 266 multiply to -266 and add up to 265:

-1 × 266 = -266
-1 + 266 = 265

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

x² + 265x - 266 = 0

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

(x - 1 ) (x + 266)

To summarize, since -1 and 266 multiply to -266 and add up 265, you know that the following is true:

x² + 265x - 266 = (x - 1 ) (x + 266)
