What two numbers multiply to 979 and add up to 980?

Here we answer the question: "What two numbers multiply to 979 and add up to 980?"

The answer to your question is:

1 and 979

Below we illustrate and prove that 1 and 979 multiply to 979 and add up to 980:

1 × 979 = 979
1 + 979 = 980

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

x² + 980x + 979 = 0

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

(x + 1 ) (x + 979)

To summarize, since 1 and 979 multiply to 979 and add up 980, you know that the following is true:

x² + 980x + 979 = (x + 1 ) (x + 979)
