What two numbers multiply to -127 and add up to -126?

Here we answer the question: "What two numbers multiply to -127 and add up to -126?"

The answer to your question is:

-127 and 1

Below we illustrate and prove that -127 and 1 multiply to -127 and add up to -126:

-127 × 1 = -127
-127 + 1 = -126

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

x² - 126x - 127 = 0

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

(x - 127 ) (x + 1)

To summarize, since -127 and 1 multiply to -127 and add up -126, you know that the following is true:

x² - 126x - 127 = (x - 127 ) (x + 1)
