What two numbers multiply to 392 and add up to -102?

Here we answer the question: "What two numbers multiply to 392 and add up to -102?"

The answer to your question is:

-98 and -4

Below we illustrate and prove that -98 and -4 multiply to 392 and add up to -102:

-98 × -4 = 392
-98 + -4 = -102

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

x² - 102x + 392 = 0

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

(x - 98 ) (x - 4)

To summarize, since -98 and -4 multiply to 392 and add up -102, you know that the following is true:

x² - 102x + 392 = (x - 98 ) (x - 4)
