What two numbers multiply to 440 and add up to 42?

Here we answer the question: "What two numbers multiply to 440 and add up to 42?"

The answer to your question is:

20 and 22

Below we illustrate and prove that 20 and 22 multiply to 440 and add up to 42:

20 × 22 = 440
20 + 22 = 42

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

x² + 42x + 440 = 0

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

(x + 20 ) (x + 22)

To summarize, since 20 and 22 multiply to 440 and add up 42, you know that the following is true:

x² + 42x + 440 = (x + 20 ) (x + 22)
