What two numbers multiply to 553 and add up to 86?

Here we answer the question: "What two numbers multiply to 553 and add up to 86?"

The answer to your question is:

7 and 79

Below we illustrate and prove that 7 and 79 multiply to 553 and add up to 86:

7 × 79 = 553
7 + 79 = 86

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

x² + 86x + 553 = 0

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

(x + 7 ) (x + 79)

To summarize, since 7 and 79 multiply to 553 and add up 86, you know that the following is true:

x² + 86x + 553 = (x + 7 ) (x + 79)
