What two numbers multiply to 840 and add up to 146?

Here we answer the question: "What two numbers multiply to 840 and add up to 146?"

The answer to your question is:

6 and 140

Below we illustrate and prove that 6 and 140 multiply to 840 and add up to 146:

6 × 140 = 840
6 + 140 = 146

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

x² + 146x + 840 = 0

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

(x + 6 ) (x + 140)

To summarize, since 6 and 140 multiply to 840 and add up 146, you know that the following is true:

x² + 146x + 840 = (x + 6 ) (x + 140)
