What two numbers multiply to 636 and add up to -163?

Here we answer the question: "What two numbers multiply to 636 and add up to -163?"

The answer to your question is:

-159 and -4

Below we illustrate and prove that -159 and -4 multiply to 636 and add up to -163:

-159 × -4 = 636
-159 + -4 = -163

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

x² - 163x + 636 = 0

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

(x - 159 ) (x - 4)

To summarize, since -159 and -4 multiply to 636 and add up -163, you know that the following is true:

x² - 163x + 636 = (x - 159 ) (x - 4)
