What two numbers multiply to -342 and add up to -51?

Here we answer the question: "What two numbers multiply to -342 and add up to -51?"

The answer to your question is:

-57 and 6

Below we illustrate and prove that -57 and 6 multiply to -342 and add up to -51:

-57 × 6 = -342
-57 + 6 = -51

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

x² - 51x - 342 = 0

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

(x - 57 ) (x + 6)

To summarize, since -57 and 6 multiply to -342 and add up -51, you know that the following is true:

x² - 51x - 342 = (x - 57 ) (x + 6)
