What two numbers multiply to -654 and add up to 215?

Here we answer the question: "What two numbers multiply to -654 and add up to 215?"

The answer to your question is:

-3 and 218

Below we illustrate and prove that -3 and 218 multiply to -654 and add up to 215:

-3 × 218 = -654
-3 + 218 = 215

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

x² + 215x - 654 = 0

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

(x - 3 ) (x + 218)

To summarize, since -3 and 218 multiply to -654 and add up 215, you know that the following is true:

x² + 215x - 654 = (x - 3 ) (x + 218)
