What two numbers multiply to 640 and add up to 164?

Here we answer the question: "What two numbers multiply to 640 and add up to 164?"

The answer to your question is:

4 and 160

Below we illustrate and prove that 4 and 160 multiply to 640 and add up to 164:

4 × 160 = 640
4 + 160 = 164

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

x² + 164x + 640 = 0

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

(x + 4 ) (x + 160)

To summarize, since 4 and 160 multiply to 640 and add up 164, you know that the following is true:

x² + 164x + 640 = (x + 4 ) (x + 160)
