What two numbers multiply to -556 and add up to 135?

Here we answer the question: "What two numbers multiply to -556 and add up to 135?"

The answer to your question is:

-4 and 139

Below we illustrate and prove that -4 and 139 multiply to -556 and add up to 135:

-4 × 139 = -556
-4 + 139 = 135

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

x² + 135x - 556 = 0

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

(x - 4 ) (x + 139)

To summarize, since -4 and 139 multiply to -556 and add up 135, you know that the following is true:

x² + 135x - 556 = (x - 4 ) (x + 139)
