What two numbers multiply to 900 and add up to -60?

Here we answer the question: "What two numbers multiply to 900 and add up to -60?"

The answer to your question is:

-30 and -30

Below we illustrate and prove that -30 and -30 multiply to 900 and add up to -60:

-30 × -30 = 900
-30 + -30 = -60

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

x² - 60x + 900 = 0

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

(x - 30 ) (x - 30)

To summarize, since -30 and -30 multiply to 900 and add up -60, you know that the following is true:

x² - 60x + 900 = (x - 30 ) (x - 30)
