What two numbers multiply to 638 and add up to -69?

Here we answer the question: "What two numbers multiply to 638 and add up to -69?"

The answer to your question is:

-58 and -11

Below we illustrate and prove that -58 and -11 multiply to 638 and add up to -69:

-58 × -11 = 638
-58 + -11 = -69

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

x² - 69x + 638 = 0

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

(x - 58 ) (x - 11)

To summarize, since -58 and -11 multiply to 638 and add up -69, you know that the following is true:

x² - 69x + 638 = (x - 58 ) (x - 11)
