What two numbers multiply to 78 and add up to 79?

Here we answer the question: "What two numbers multiply to 78 and add up to 79?"

The answer to your question is:

1 and 78

Below we illustrate and prove that 1 and 78 multiply to 78 and add up to 79:

1 × 78 = 78
1 + 78 = 79

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

x² + 79x + 78 = 0

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

(x + 1 ) (x + 78)

To summarize, since 1 and 78 multiply to 78 and add up 79, you know that the following is true:

x² + 79x + 78 = (x + 1 ) (x + 78)
