What two numbers multiply to -450 and add up to -7?

Here we answer the question: "What two numbers multiply to -450 and add up to -7?"

The answer to your question is:

-25 and 18

Below we illustrate and prove that -25 and 18 multiply to -450 and add up to -7:

-25 × 18 = -450
-25 + 18 = -7

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

x² - 7x - 450 = 0

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

(x - 25 ) (x + 18)

To summarize, since -25 and 18 multiply to -450 and add up -7, you know that the following is true:

x² - 7x - 450 = (x - 25 ) (x + 18)
