What two numbers multiply to 671 and add up to 72?

Here we answer the question: "What two numbers multiply to 671 and add up to 72?"

The answer to your question is:

11 and 61

Below we illustrate and prove that 11 and 61 multiply to 671 and add up to 72:

11 × 61 = 671
11 + 61 = 72

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

x² + 72x + 671 = 0

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

(x + 11 ) (x + 61)

To summarize, since 11 and 61 multiply to 671 and add up 72, you know that the following is true:

x² + 72x + 671 = (x + 11 ) (x + 61)
