What two numbers multiply to -651 and add up to 214?

Here we answer the question: "What two numbers multiply to -651 and add up to 214?"

The answer to your question is:

-3 and 217

Below we illustrate and prove that -3 and 217 multiply to -651 and add up to 214:

-3 × 217 = -651
-3 + 217 = 214

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

x² + 214x - 651 = 0

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

(x - 3 ) (x + 217)

To summarize, since -3 and 217 multiply to -651 and add up 214, you know that the following is true:

x² + 214x - 651 = (x - 3 ) (x + 217)
