What two numbers multiply to -138 and add up to -67?

Here we answer the question: "What two numbers multiply to -138 and add up to -67?"

The answer to your question is:

-69 and 2

Below we illustrate and prove that -69 and 2 multiply to -138 and add up to -67:

-69 × 2 = -138
-69 + 2 = -67

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

x² - 67x - 138 = 0

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

(x - 69 ) (x + 2)

To summarize, since -69 and 2 multiply to -138 and add up -67, you know that the following is true:

x² - 67x - 138 = (x - 69 ) (x + 2)
