What two numbers multiply to 720 and add up to -149?

Here we answer the question: "What two numbers multiply to 720 and add up to -149?"

The answer to your question is:

-144 and -5

Below we illustrate and prove that -144 and -5 multiply to 720 and add up to -149:

-144 × -5 = 720
-144 + -5 = -149

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

x² - 149x + 720 = 0

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

(x - 144 ) (x - 5)

To summarize, since -144 and -5 multiply to 720 and add up -149, you know that the following is true:

x² - 149x + 720 = (x - 144 ) (x - 5)
