What two numbers multiply to 71 and add up to -72?

Here we answer the question: "What two numbers multiply to 71 and add up to -72?"

The answer to your question is:

-71 and -1

Below we illustrate and prove that -71 and -1 multiply to 71 and add up to -72:

-71 × -1 = 71
-71 + -1 = -72

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

x² - 72x + 71 = 0

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

(x - 71 ) (x - 1)

To summarize, since -71 and -1 multiply to 71 and add up -72, you know that the following is true:

x² - 72x + 71 = (x - 71 ) (x - 1)
