What two numbers multiply to 120 and add up to 43?

Here we answer the question: "What two numbers multiply to 120 and add up to 43?"

The answer to your question is:

3 and 40

Below we illustrate and prove that 3 and 40 multiply to 120 and add up to 43:

3 × 40 = 120
3 + 40 = 43

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

x² + 43x + 120 = 0

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

(x + 3 ) (x + 40)

To summarize, since 3 and 40 multiply to 120 and add up 43, you know that the following is true:

x² + 43x + 120 = (x + 3 ) (x + 40)
