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:

-18 and 25

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

-18 × 25 = -450
-18 + 25 = 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 - 18 ) (x + 25)

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

x² + 7x - 450 = (x - 18 ) (x + 25)
