What two numbers multiply to -306 and add up to 45?

Here we answer the question: "What two numbers multiply to -306 and add up to 45?"

The answer to your question is:

-6 and 51

Below we illustrate and prove that -6 and 51 multiply to -306 and add up to 45:

-6 × 51 = -306
-6 + 51 = 45

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

x² + 45x - 306 = 0

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

(x - 6 ) (x + 51)

To summarize, since -6 and 51 multiply to -306 and add up 45, you know that the following is true:

x² + 45x - 306 = (x - 6 ) (x + 51)
