What two numbers multiply to -450 and add up to -85?

Here we answer the question: "What two numbers multiply to -450 and add up to -85?"

The answer to your question is:

-90 and 5

Below we illustrate and prove that -90 and 5 multiply to -450 and add up to -85:

-90 × 5 = -450
-90 + 5 = -85

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

x² - 85x - 450 = 0

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

(x - 90 ) (x + 5)

To summarize, since -90 and 5 multiply to -450 and add up -85, you know that the following is true:

x² - 85x - 450 = (x - 90 ) (x + 5)
