What two numbers multiply to -450 and add up to 449?

Here we answer the question: "What two numbers multiply to -450 and add up to 449?"

The answer to your question is:

-1 and 450

Below we illustrate and prove that -1 and 450 multiply to -450 and add up to 449:

-1 × 450 = -450
-1 + 450 = 449

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

x² + 449x - 450 = 0

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

(x - 1 ) (x + 450)

To summarize, since -1 and 450 multiply to -450 and add up 449, you know that the following is true:

x² + 449x - 450 = (x - 1 ) (x + 450)
