What two numbers multiply to -135 and add up to 134?

Here we answer the question: "What two numbers multiply to -135 and add up to 134?"

The answer to your question is:

-1 and 135

Below we illustrate and prove that -1 and 135 multiply to -135 and add up to 134:

-1 × 135 = -135
-1 + 135 = 134

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

x² + 134x - 135 = 0

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

(x - 1 ) (x + 135)

To summarize, since -1 and 135 multiply to -135 and add up 134, you know that the following is true:

x² + 134x - 135 = (x - 1 ) (x + 135)
