What two numbers multiply to 810 and add up to -69?

Here we answer the question: "What two numbers multiply to 810 and add up to -69?"

The answer to your question is:

-54 and -15

Below we illustrate and prove that -54 and -15 multiply to 810 and add up to -69:

-54 × -15 = 810
-54 + -15 = -69

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

x² - 69x + 810 = 0

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

(x - 54 ) (x - 15)

To summarize, since -54 and -15 multiply to 810 and add up -69, you know that the following is true:

x² - 69x + 810 = (x - 54 ) (x - 15)
