What two numbers multiply to 165 and add up to 166?

Here we answer the question: "What two numbers multiply to 165 and add up to 166?"

The answer to your question is:

1 and 165

Below we illustrate and prove that 1 and 165 multiply to 165 and add up to 166:

1 × 165 = 165
1 + 165 = 166

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

x² + 166x + 165 = 0

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

(x + 1 ) (x + 165)

To summarize, since 1 and 165 multiply to 165 and add up 166, you know that the following is true:

x² + 166x + 165 = (x + 1 ) (x + 165)
