What two numbers multiply to -655 and add up to 126?

Here we answer the question: "What two numbers multiply to -655 and add up to 126?"

The answer to your question is:

-5 and 131

Below we illustrate and prove that -5 and 131 multiply to -655 and add up to 126:

-5 × 131 = -655
-5 + 131 = 126

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

x² + 126x - 655 = 0

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

(x - 5 ) (x + 131)

To summarize, since -5 and 131 multiply to -655 and add up 126, you know that the following is true:

x² + 126x - 655 = (x - 5 ) (x + 131)
