What two numbers multiply to 438 and add up to -79?

Here we answer the question: "What two numbers multiply to 438 and add up to -79?"

The answer to your question is:

-73 and -6

Below we illustrate and prove that -73 and -6 multiply to 438 and add up to -79:

-73 × -6 = 438
-73 + -6 = -79

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

x² - 79x + 438 = 0

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

(x - 73 ) (x - 6)

To summarize, since -73 and -6 multiply to 438 and add up -79, you know that the following is true:

x² - 79x + 438 = (x - 73 ) (x - 6)
