Here we answer the question: "What two numbers multiply to 720 and add up to 149?"
The answer to your question is:
5 and 144
Below we illustrate and prove that 5 and 144 multiply to 720 and add up to 149:
5 × 144 = 720
5 + 144 = 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 + 5 ) (x + 144)
To summarize, since 5 and 144 multiply to 720 and add up 149, you know that the following is true:
x2 + 149x + 720 = (x + 5 ) (x + 144)
