What two numbers multiply to 168 and add up to 169?

Here we answer the question: "What two numbers multiply to 168 and add up to 169?"

The answer to your question is:

1 and 168

Below we illustrate and prove that 1 and 168 multiply to 168 and add up to 169:

1 × 168 = 168
1 + 168 = 169

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

x² + 169x + 168 = 0

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

(x + 1 ) (x + 168)

To summarize, since 1 and 168 multiply to 168 and add up 169, you know that the following is true:

x² + 169x + 168 = (x + 1 ) (x + 168)
