What two numbers multiply to 980 and add up to 981?

Here we answer the question: "What two numbers multiply to 980 and add up to 981?"

The answer to your question is:

1 and 980

Below we illustrate and prove that 1 and 980 multiply to 980 and add up to 981:

1 × 980 = 980
1 + 980 = 981

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

x² + 981x + 980 = 0

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

(x + 1 ) (x + 980)

To summarize, since 1 and 980 multiply to 980 and add up 981, you know that the following is true:

x² + 981x + 980 = (x + 1 ) (x + 980)
