What two numbers multiply to -416 and add up to 206?

Here we answer the question: "What two numbers multiply to -416 and add up to 206?"

The answer to your question is:

-2 and 208

Below we illustrate and prove that -2 and 208 multiply to -416 and add up to 206:

-2 × 208 = -416
-2 + 208 = 206

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

x² + 206x - 416 = 0

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

(x - 2 ) (x + 208)

To summarize, since -2 and 208 multiply to -416 and add up 206, you know that the following is true:

x² + 206x - 416 = (x - 2 ) (x + 208)
