What two numbers multiply to 550 and add up to 115?

Here we answer the question: "What two numbers multiply to 550 and add up to 115?"

The answer to your question is:

5 and 110

Below we illustrate and prove that 5 and 110 multiply to 550 and add up to 115:

5 × 110 = 550
5 + 110 = 115

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

x² + 115x + 550 = 0

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

(x + 5 ) (x + 110)

To summarize, since 5 and 110 multiply to 550 and add up 115, you know that the following is true:

x² + 115x + 550 = (x + 5 ) (x + 110)
