What two numbers multiply to -136 and add up to -66?

Here we answer the question: "What two numbers multiply to -136 and add up to -66?"

The answer to your question is:

-68 and 2

Below we illustrate and prove that -68 and 2 multiply to -136 and add up to -66:

-68 × 2 = -136
-68 + 2 = -66

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

x² - 66x - 136 = 0

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

(x - 68 ) (x + 2)

To summarize, since -68 and 2 multiply to -136 and add up -66, you know that the following is true:

x² - 66x - 136 = (x - 68 ) (x + 2)
