What two numbers multiply to -676 and add up to 165?

Here we answer the question: "What two numbers multiply to -676 and add up to 165?"

The answer to your question is:

-4 and 169

Below we illustrate and prove that -4 and 169 multiply to -676 and add up to 165:

-4 × 169 = -676
-4 + 169 = 165

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

x² + 165x - 676 = 0

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

(x - 4 ) (x + 169)

To summarize, since -4 and 169 multiply to -676 and add up 165, you know that the following is true:

x² + 165x - 676 = (x - 4 ) (x + 169)
