What two numbers multiply to 780 and add up to 67?

Here we answer the question: "What two numbers multiply to 780 and add up to 67?"

The answer to your question is:

15 and 52

Below we illustrate and prove that 15 and 52 multiply to 780 and add up to 67:

15 × 52 = 780
15 + 52 = 67

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

x² + 67x + 780 = 0

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

(x + 15 ) (x + 52)

To summarize, since 15 and 52 multiply to 780 and add up 67, you know that the following is true:

x² + 67x + 780 = (x + 15 ) (x + 52)
