What two numbers multiply to -136 and add up to 135?

Here we answer the question: "What two numbers multiply to -136 and add up to 135?"

The answer to your question is:

-1 and 136

Below we illustrate and prove that -1 and 136 multiply to -136 and add up to 135:

-1 × 136 = -136
-1 + 136 = 135

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

x² + 135x - 136 = 0

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

(x - 1 ) (x + 136)

To summarize, since -1 and 136 multiply to -136 and add up 135, you know that the following is true:

x² + 135x - 136 = (x - 1 ) (x + 136)
