Here we answer the question: "What two numbers multiply to 720 and add up to 126?"

The answer to your question is:

6 and 120


Below we illustrate and prove that 6 and 120 multiply to 720 and add up to 126:

6 × 120 = 720
6 + 120 = 126

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

x2 + 126x + 720 = 0

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

(x + 6 ) (x + 120)

To summarize, since 6 and 120 multiply to 720 and add up 126, you know that the following is true:

x2 + 126x + 720 = (x + 6 ) (x + 120)
