What two numbers multiply to 402 and add up to 403?

Here we answer the question: "What two numbers multiply to 402 and add up to 403?"

The answer to your question is:

1 and 402

Below we illustrate and prove that 1 and 402 multiply to 402 and add up to 403:

1 × 402 = 402
1 + 402 = 403

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

x² + 403x + 402 = 0

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

(x + 1 ) (x + 402)

To summarize, since 1 and 402 multiply to 402 and add up 403, you know that the following is true:

x² + 403x + 402 = (x + 1 ) (x + 402)
