What two numbers multiply to 450 and add up to -81?

Here we answer the question: "What two numbers multiply to 450 and add up to -81?"

The answer to your question is:

-75 and -6

Below we illustrate and prove that -75 and -6 multiply to 450 and add up to -81:

-75 × -6 = 450
-75 + -6 = -81

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

x² - 81x + 450 = 0

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

(x - 75 ) (x - 6)

To summarize, since -75 and -6 multiply to 450 and add up -81, you know that the following is true:

x² - 81x + 450 = (x - 75 ) (x - 6)
