What two numbers multiply to 144 and add up to 51?

Here we answer the question: "What two numbers multiply to 144 and add up to 51?"

The answer to your question is:

3 and 48

Below we illustrate and prove that 3 and 48 multiply to 144 and add up to 51:

3 × 48 = 144
3 + 48 = 51

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

x² + 51x + 144 = 0

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

(x + 3 ) (x + 48)

To summarize, since 3 and 48 multiply to 144 and add up 51, you know that the following is true:

x² + 51x + 144 = (x + 3 ) (x + 48)
