What two numbers multiply to -55 and add up to 6?

Here we answer the question: "What two numbers multiply to -55 and add up to 6?"

The answer to your question is:

-5 and 11

Below we illustrate and prove that -5 and 11 multiply to -55 and add up to 6:

-5 × 11 = -55
-5 + 11 = 6

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

x² + 6x - 55 = 0

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

(x - 5 ) (x + 11)

To summarize, since -5 and 11 multiply to -55 and add up 6, you know that the following is true:

x² + 6x - 55 = (x - 5 ) (x + 11)
