What two numbers multiply to 781 and add up to 82?

Here we answer the question: "What two numbers multiply to 781 and add up to 82?"

The answer to your question is:

11 and 71

Below we illustrate and prove that 11 and 71 multiply to 781 and add up to 82:

11 × 71 = 781
11 + 71 = 82

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

x² + 82x + 781 = 0

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

(x + 11 ) (x + 71)

To summarize, since 11 and 71 multiply to 781 and add up 82, you know that the following is true:

x² + 82x + 781 = (x + 11 ) (x + 71)
