What two numbers multiply to 550 and add up to -65?

Here we answer the question: "What two numbers multiply to 550 and add up to -65?"

The answer to your question is:

-55 and -10

Below we illustrate and prove that -55 and -10 multiply to 550 and add up to -65:

-55 × -10 = 550
-55 + -10 = -65

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

x² - 65x + 550 = 0

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

(x - 55 ) (x - 10)

To summarize, since -55 and -10 multiply to 550 and add up -65, you know that the following is true:

x² - 65x + 550 = (x - 55 ) (x - 10)
