What two numbers multiply to 144 and add up to -145?

Here we answer the question: "What two numbers multiply to 144 and add up to -145?"

The answer to your question is:

-144 and -1

Below we illustrate and prove that -144 and -1 multiply to 144 and add up to -145:

-144 × -1 = 144
-144 + -1 = -145

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

x² - 145x + 144 = 0

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

(x - 144 ) (x - 1)

To summarize, since -144 and -1 multiply to 144 and add up -145, you know that the following is true:

x² - 145x + 144 = (x - 144 ) (x - 1)
