What two numbers multiply to 810 and add up to 57?

Here we answer the question: "What two numbers multiply to 810 and add up to 57?"

The answer to your question is:

27 and 30

Below we illustrate and prove that 27 and 30 multiply to 810 and add up to 57:

27 × 30 = 810
27 + 30 = 57

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

x² + 57x + 810 = 0

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

(x + 27 ) (x + 30)

To summarize, since 27 and 30 multiply to 810 and add up 57, you know that the following is true:

x² + 57x + 810 = (x + 27 ) (x + 30)
