What two numbers multiply to 138 and add up to 49?

Here we answer the question: "What two numbers multiply to 138 and add up to 49?"

The answer to your question is:

3 and 46

Below we illustrate and prove that 3 and 46 multiply to 138 and add up to 49:

3 × 46 = 138
3 + 46 = 49

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

x² + 49x + 138 = 0

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

(x + 3 ) (x + 46)

To summarize, since 3 and 46 multiply to 138 and add up 49, you know that the following is true:

x² + 49x + 138 = (x + 3 ) (x + 46)
