What two numbers multiply to -156 and add up to -1?

Here we answer the question: "What two numbers multiply to -156 and add up to -1?"

The answer to your question is:

-13 and 12

Below we illustrate and prove that -13 and 12 multiply to -156 and add up to -1:

-13 × 12 = -156
-13 + 12 = -1

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

x² - 1x - 156 = 0

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

(x - 13 ) (x + 12)

To summarize, since -13 and 12 multiply to -156 and add up -1, you know that the following is true:

x² - 1x - 156 = (x - 13 ) (x + 12)
