What two numbers multiply to 900 and add up to -61?

Here we answer the question: "What two numbers multiply to 900 and add up to -61?"

The answer to your question is:

-36 and -25

Below we illustrate and prove that -36 and -25 multiply to 900 and add up to -61:

-36 × -25 = 900
-36 + -25 = -61

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

x² - 61x + 900 = 0

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

(x - 36 ) (x - 25)

To summarize, since -36 and -25 multiply to 900 and add up -61, you know that the following is true:

x² - 61x + 900 = (x - 36 ) (x - 25)
