What two numbers multiply to 991 and add up to 992?

Here we answer the question: "What two numbers multiply to 991 and add up to 992?"

The answer to your question is:

1 and 991

Below we illustrate and prove that 1 and 991 multiply to 991 and add up to 992:

1 × 991 = 991
1 + 991 = 992

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

x² + 992x + 991 = 0

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

(x + 1 ) (x + 991)

To summarize, since 1 and 991 multiply to 991 and add up 992, you know that the following is true:

x² + 992x + 991 = (x + 1 ) (x + 991)
