What two numbers multiply to 528 and add up to 74?

Here we answer the question: "What two numbers multiply to 528 and add up to 74?"

The answer to your question is:

8 and 66

Below we illustrate and prove that 8 and 66 multiply to 528 and add up to 74:

8 × 66 = 528
8 + 66 = 74

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

x² + 74x + 528 = 0

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

(x + 8 ) (x + 66)

To summarize, since 8 and 66 multiply to 528 and add up 74, you know that the following is true:

x² + 74x + 528 = (x + 8 ) (x + 66)
