What two numbers multiply to 576 and add up to 73?

Here we answer the question: "What two numbers multiply to 576 and add up to 73?"

The answer to your question is:

9 and 64

Below we illustrate and prove that 9 and 64 multiply to 576 and add up to 73:

9 × 64 = 576
9 + 64 = 73

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

x² + 73x + 576 = 0

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

(x + 9 ) (x + 64)

To summarize, since 9 and 64 multiply to 576 and add up 73, you know that the following is true:

x² + 73x + 576 = (x + 9 ) (x + 64)
