What two numbers multiply to 645 and add up to -134?

Here we answer the question: "What two numbers multiply to 645 and add up to -134?"

The answer to your question is:

-129 and -5

Below we illustrate and prove that -129 and -5 multiply to 645 and add up to -134:

-129 × -5 = 645
-129 + -5 = -134

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

x² - 134x + 645 = 0

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

(x - 129 ) (x - 5)

To summarize, since -129 and -5 multiply to 645 and add up -134, you know that the following is true:

x² - 134x + 645 = (x - 129 ) (x - 5)
