What two numbers multiply to -273 and add up to 8?

Here we answer the question: "What two numbers multiply to -273 and add up to 8?"

The answer to your question is:

-13 and 21

Below we illustrate and prove that -13 and 21 multiply to -273 and add up to 8:

-13 × 21 = -273
-13 + 21 = 8

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

x² + 8x - 273 = 0

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

(x - 13 ) (x + 21)

To summarize, since -13 and 21 multiply to -273 and add up 8, you know that the following is true:

x² + 8x - 273 = (x - 13 ) (x + 21)
