What two numbers multiply to -300 and add up to 55?

Here we answer the question: "What two numbers multiply to -300 and add up to 55?"

The answer to your question is:

-5 and 60

Below we illustrate and prove that -5 and 60 multiply to -300 and add up to 55:

-5 × 60 = -300
-5 + 60 = 55

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

x² + 55x - 300 = 0

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

(x - 5 ) (x + 60)

To summarize, since -5 and 60 multiply to -300 and add up 55, you know that the following is true:

x² + 55x - 300 = (x - 5 ) (x + 60)
