What two numbers multiply to 784 and add up to 65?

Here we answer the question: "What two numbers multiply to 784 and add up to 65?"

The answer to your question is:

16 and 49

Below we illustrate and prove that 16 and 49 multiply to 784 and add up to 65:

16 × 49 = 784
16 + 49 = 65

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

x² + 65x + 784 = 0

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

(x + 16 ) (x + 49)

To summarize, since 16 and 49 multiply to 784 and add up 65, you know that the following is true:

x² + 65x + 784 = (x + 16 ) (x + 49)
