What two numbers multiply to 840 and add up to 58?

Here we answer the question: "What two numbers multiply to 840 and add up to 58?"

The answer to your question is:

28 and 30

Below we illustrate and prove that 28 and 30 multiply to 840 and add up to 58:

28 × 30 = 840
28 + 30 = 58

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

x² + 58x + 840 = 0

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

(x + 28 ) (x + 30)

To summarize, since 28 and 30 multiply to 840 and add up 58, you know that the following is true:

x² + 58x + 840 = (x + 28 ) (x + 30)
