What two numbers multiply to 820 and add up to 61?

Here we answer the question: "What two numbers multiply to 820 and add up to 61?"

The answer to your question is:

20 and 41

Below we illustrate and prove that 20 and 41 multiply to 820 and add up to 61:

20 × 41 = 820
20 + 41 = 61

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

x² + 61x + 820 = 0

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

(x + 20 ) (x + 41)

To summarize, since 20 and 41 multiply to 820 and add up 61, you know that the following is true:

x² + 61x + 820 = (x + 20 ) (x + 41)
