What two numbers multiply to 256 and add up to 68?

Here we answer the question: "What two numbers multiply to 256 and add up to 68?"

The answer to your question is:

4 and 64

Below we illustrate and prove that 4 and 64 multiply to 256 and add up to 68:

4 × 64 = 256
4 + 64 = 68

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

x² + 68x + 256 = 0

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

(x + 4 ) (x + 64)

To summarize, since 4 and 64 multiply to 256 and add up 68, you know that the following is true:

x² + 68x + 256 = (x + 4 ) (x + 64)
