What two numbers multiply to 651 and add up to -52?

Here we answer the question: "What two numbers multiply to 651 and add up to -52?"

The answer to your question is:

-31 and -21

Below we illustrate and prove that -31 and -21 multiply to 651 and add up to -52:

-31 × -21 = 651
-31 + -21 = -52

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

x² - 52x + 651 = 0

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

(x - 31 ) (x - 21)

To summarize, since -31 and -21 multiply to 651 and add up -52, you know that the following is true:

x² - 52x + 651 = (x - 31 ) (x - 21)
