What two numbers multiply to 630 and add up to 111?

Here we answer the question: "What two numbers multiply to 630 and add up to 111?"

The answer to your question is:

6 and 105

Below we illustrate and prove that 6 and 105 multiply to 630 and add up to 111:

6 × 105 = 630
6 + 105 = 111

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

x² + 111x + 630 = 0

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

(x + 6 ) (x + 105)

To summarize, since 6 and 105 multiply to 630 and add up 111, you know that the following is true:

x² + 111x + 630 = (x + 6 ) (x + 105)
