What two numbers multiply to 645 and add up to 58?

Here we answer the question: "What two numbers multiply to 645 and add up to 58?"

The answer to your question is:

15 and 43

Below we illustrate and prove that 15 and 43 multiply to 645 and add up to 58:

15 × 43 = 645
15 + 43 = 58

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

x² + 58x + 645 = 0

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

(x + 15 ) (x + 43)

To summarize, since 15 and 43 multiply to 645 and add up 58, you know that the following is true:

x² + 58x + 645 = (x + 15 ) (x + 43)
