What two numbers multiply to 140 and add up to 39?

Here we answer the question: "What two numbers multiply to 140 and add up to 39?"

The answer to your question is:

4 and 35

Below we illustrate and prove that 4 and 35 multiply to 140 and add up to 39:

4 × 35 = 140
4 + 35 = 39

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

x² + 39x + 140 = 0

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

(x + 4 ) (x + 35)

To summarize, since 4 and 35 multiply to 140 and add up 39, you know that the following is true:

x² + 39x + 140 = (x + 4 ) (x + 35)
