What two numbers multiply to 450 and add up to -45?

Here we answer the question: "What two numbers multiply to 450 and add up to -45?"

The answer to your question is:

-30 and -15

Below we illustrate and prove that -30 and -15 multiply to 450 and add up to -45:

-30 × -15 = 450
-30 + -15 = -45

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

x² - 45x + 450 = 0

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

(x - 30 ) (x - 15)

To summarize, since -30 and -15 multiply to 450 and add up -45, you know that the following is true:

x² - 45x + 450 = (x - 30 ) (x - 15)
