What two numbers multiply to -756 and add up to 51?

Here we answer the question: "What two numbers multiply to -756 and add up to 51?"

The answer to your question is:

-12 and 63

Below we illustrate and prove that -12 and 63 multiply to -756 and add up to 51:

-12 × 63 = -756
-12 + 63 = 51

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

x² + 51x - 756 = 0

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

(x - 12 ) (x + 63)

To summarize, since -12 and 63 multiply to -756 and add up 51, you know that the following is true:

x² + 51x - 756 = (x - 12 ) (x + 63)
