What two numbers multiply to 784 and add up to 200?

Here we answer the question: "What two numbers multiply to 784 and add up to 200?"

The answer to your question is:

4 and 196

Below we illustrate and prove that 4 and 196 multiply to 784 and add up to 200:

4 × 196 = 784
4 + 196 = 200

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

x² + 200x + 784 = 0

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

(x + 4 ) (x + 196)

To summarize, since 4 and 196 multiply to 784 and add up 200, you know that the following is true:

x² + 200x + 784 = (x + 4 ) (x + 196)
