What two numbers multiply to 780 and add up to 56?

Here we answer the question: "What two numbers multiply to 780 and add up to 56?"

The answer to your question is:

26 and 30

Below we illustrate and prove that 26 and 30 multiply to 780 and add up to 56:

26 × 30 = 780
26 + 30 = 56

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

x² + 56x + 780 = 0

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

(x + 26 ) (x + 30)

To summarize, since 26 and 30 multiply to 780 and add up 56, you know that the following is true:

x² + 56x + 780 = (x + 26 ) (x + 30)
