What two numbers multiply to 900 and add up to -87?

Here we answer the question: "What two numbers multiply to 900 and add up to -87?"

The answer to your question is:

-75 and -12

Below we illustrate and prove that -75 and -12 multiply to 900 and add up to -87:

-75 × -12 = 900
-75 + -12 = -87

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

x² - 87x + 900 = 0

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

(x - 75 ) (x - 12)

To summarize, since -75 and -12 multiply to 900 and add up -87, you know that the following is true:

x² - 87x + 900 = (x - 75 ) (x - 12)
