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:

-139 and 4

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

-139 × 4 = -556
-139 + 4 = -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 - 139 ) (x + 4)

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

x² - 135x - 556 = (x - 139 ) (x + 4)
