What two numbers multiply to 840 and add up to 82?

Here we answer the question: "What two numbers multiply to 840 and add up to 82?"

The answer to your question is:

12 and 70

Below we illustrate and prove that 12 and 70 multiply to 840 and add up to 82:

12 × 70 = 840
12 + 70 = 82

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

x² + 82x + 840 = 0

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

(x + 12 ) (x + 70)

To summarize, since 12 and 70 multiply to 840 and add up 82, you know that the following is true:

x² + 82x + 840 = (x + 12 ) (x + 70)
