What two numbers multiply to 144 and add up to -25?

Here we answer the question: "What two numbers multiply to 144 and add up to -25?"

The answer to your question is:

-16 and -9

Below we illustrate and prove that -16 and -9 multiply to 144 and add up to -25:

-16 × -9 = 144
-16 + -9 = -25

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

x² - 25x + 144 = 0

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

(x - 16 ) (x - 9)

To summarize, since -16 and -9 multiply to 144 and add up -25, you know that the following is true:

x² - 25x + 144 = (x - 16 ) (x - 9)
