What two numbers multiply to 495 and add up to 64?

Here we answer the question: "What two numbers multiply to 495 and add up to 64?"

The answer to your question is:

9 and 55

Below we illustrate and prove that 9 and 55 multiply to 495 and add up to 64:

9 × 55 = 495
9 + 55 = 64

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

x² + 64x + 495 = 0

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

(x + 9 ) (x + 55)

To summarize, since 9 and 55 multiply to 495 and add up 64, you know that the following is true:

x² + 64x + 495 = (x + 9 ) (x + 55)
