What two numbers multiply to 552 and add up to 77?

Here we answer the question: "What two numbers multiply to 552 and add up to 77?"

The answer to your question is:

8 and 69

Below we illustrate and prove that 8 and 69 multiply to 552 and add up to 77:

8 × 69 = 552
8 + 69 = 77

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

x² + 77x + 552 = 0

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

(x + 8 ) (x + 69)

To summarize, since 8 and 69 multiply to 552 and add up 77, you know that the following is true:

x² + 77x + 552 = (x + 8 ) (x + 69)
