What two numbers multiply to 812 and add up to 123?

Here we answer the question: "What two numbers multiply to 812 and add up to 123?"

The answer to your question is:

7 and 116

Below we illustrate and prove that 7 and 116 multiply to 812 and add up to 123:

7 × 116 = 812
7 + 116 = 123

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

x² + 123x + 812 = 0

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

(x + 7 ) (x + 116)

To summarize, since 7 and 116 multiply to 812 and add up 123, you know that the following is true:

x² + 123x + 812 = (x + 7 ) (x + 116)
