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:

-6 and 57

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

-6 × 57 = -342
-6 + 57 = 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 - 6 ) (x + 57)

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

x² + 51x - 342 = (x - 6 ) (x + 57)
