What two numbers multiply to 406 and add up to -205?

Here we answer the question: "What two numbers multiply to 406 and add up to -205?"

The answer to your question is:

-203 and -2

Below we illustrate and prove that -203 and -2 multiply to 406 and add up to -205:

-203 × -2 = 406
-203 + -2 = -205

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

x² - 205x + 406 = 0

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

(x - 203 ) (x - 2)

To summarize, since -203 and -2 multiply to 406 and add up -205, you know that the following is true:

x² - 205x + 406 = (x - 203 ) (x - 2)
