What two numbers multiply to -450 and add up to 223?

Here we answer the question: "What two numbers multiply to -450 and add up to 223?"

The answer to your question is:

-2 and 225

Below we illustrate and prove that -2 and 225 multiply to -450 and add up to 223:

-2 × 225 = -450
-2 + 225 = 223

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

x² + 223x - 450 = 0

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

(x - 2 ) (x + 225)

To summarize, since -2 and 225 multiply to -450 and add up 223, you know that the following is true:

x² + 223x - 450 = (x - 2 ) (x + 225)
