What two numbers multiply to 450 and add up to -55?

Here we answer the question: "What two numbers multiply to 450 and add up to -55?"

The answer to your question is:

-45 and -10

Below we illustrate and prove that -45 and -10 multiply to 450 and add up to -55:

-45 × -10 = 450
-45 + -10 = -55

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

x² - 55x + 450 = 0

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

(x - 45 ) (x - 10)

To summarize, since -45 and -10 multiply to 450 and add up -55, you know that the following is true:

x² - 55x + 450 = (x - 45 ) (x - 10)
