What two numbers multiply to 440 and add up to 63?

Here we answer the question: "What two numbers multiply to 440 and add up to 63?"

The answer to your question is:

8 and 55

Below we illustrate and prove that 8 and 55 multiply to 440 and add up to 63:

8 × 55 = 440
8 + 55 = 63

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

x² + 63x + 440 = 0

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

(x + 8 ) (x + 55)

To summarize, since 8 and 55 multiply to 440 and add up 63, you know that the following is true:

x² + 63x + 440 = (x + 8 ) (x + 55)
