What two numbers multiply to 990 and add up to -73?

Here we answer the question: "What two numbers multiply to 990 and add up to -73?"

The answer to your question is:

-55 and -18

Below we illustrate and prove that -55 and -18 multiply to 990 and add up to -73:

-55 × -18 = 990
-55 + -18 = -73

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

x² - 73x + 990 = 0

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

(x - 55 ) (x - 18)

To summarize, since -55 and -18 multiply to 990 and add up -73, you know that the following is true:

x² - 73x + 990 = (x - 55 ) (x - 18)
