What two numbers multiply to -144 and add up to -45?

Here we answer the question: "What two numbers multiply to -144 and add up to -45?"

The answer to your question is:

-48 and 3

Below we illustrate and prove that -48 and 3 multiply to -144 and add up to -45:

-48 × 3 = -144
-48 + 3 = -45

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

x² - 45x - 144 = 0

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

(x - 48 ) (x + 3)

To summarize, since -48 and 3 multiply to -144 and add up -45, you know that the following is true:

x² - 45x - 144 = (x - 48 ) (x + 3)
