What two numbers multiply to 936 and add up to -90?

Here we answer the question: "What two numbers multiply to 936 and add up to -90?"

The answer to your question is:

-78 and -12

Below we illustrate and prove that -78 and -12 multiply to 936 and add up to -90:

-78 × -12 = 936
-78 + -12 = -90

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

x² - 90x + 936 = 0

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

(x - 78 ) (x - 12)

To summarize, since -78 and -12 multiply to 936 and add up -90, you know that the following is true:

x² - 90x + 936 = (x - 78 ) (x - 12)
