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:

2 and 203

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

2 × 203 = 406
2 + 203 = 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 + 2 ) (x + 203)

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

x² + 205x + 406 = (x + 2 ) (x + 203)
