What two numbers multiply to -451 and add up to 450?

Here we answer the question: "What two numbers multiply to -451 and add up to 450?"

The answer to your question is:

-1 and 451

Below we illustrate and prove that -1 and 451 multiply to -451 and add up to 450:

-1 × 451 = -451
-1 + 451 = 450

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

x² + 450x - 451 = 0

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

(x - 1 ) (x + 451)

To summarize, since -1 and 451 multiply to -451 and add up 450, you know that the following is true:

x² + 450x - 451 = (x - 1 ) (x + 451)
