What two numbers multiply to -169 and add up to 0?

Here we answer the question: "What two numbers multiply to -169 and add up to 0?"

The answer to your question is:

-13 and 13

Below we illustrate and prove that -13 and 13 multiply to -169 and add up to 0:

-13 × 13 = -169
-13 + 13 = 0

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

x² + 0x - 169 = 0

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

(x - 13 ) (x + 13)

To summarize, since -13 and 13 multiply to -169 and add up 0, you know that the following is true:

x² + 0x - 169 = (x - 13 ) (x + 13)
