What two numbers multiply to 488 and add up to -126?

Here we answer the question: "What two numbers multiply to 488 and add up to -126?"

The answer to your question is:

-122 and -4

Below we illustrate and prove that -122 and -4 multiply to 488 and add up to -126:

-122 × -4 = 488
-122 + -4 = -126

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

x² - 126x + 488 = 0

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

(x - 122 ) (x - 4)

To summarize, since -122 and -4 multiply to 488 and add up -126, you know that the following is true:

x² - 126x + 488 = (x - 122 ) (x - 4)
