What two numbers multiply to -972 and add up to -69?

Here we answer the question: "What two numbers multiply to -972 and add up to -69?"

The answer to your question is:

-81 and 12

Below we illustrate and prove that -81 and 12 multiply to -972 and add up to -69:

-81 × 12 = -972
-81 + 12 = -69

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

x² - 69x - 972 = 0

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

(x - 81 ) (x + 12)

To summarize, since -81 and 12 multiply to -972 and add up -69, you know that the following is true:

x² - 69x - 972 = (x - 81 ) (x + 12)
