What two numbers multiply to 630 and add up to 57?

Here we answer the question: "What two numbers multiply to 630 and add up to 57?"

The answer to your question is:

15 and 42

Below we illustrate and prove that 15 and 42 multiply to 630 and add up to 57:

15 × 42 = 630
15 + 42 = 57

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

x² + 57x + 630 = 0

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

(x + 15 ) (x + 42)

To summarize, since 15 and 42 multiply to 630 and add up 57, you know that the following is true:

x² + 57x + 630 = (x + 15 ) (x + 42)
