What two numbers multiply to -142 and add up to 69?

Here we answer the question: "What two numbers multiply to -142 and add up to 69?"

The answer to your question is:

-2 and 71

Below we illustrate and prove that -2 and 71 multiply to -142 and add up to 69:

-2 × 71 = -142
-2 + 71 = 69

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

x² + 69x - 142 = 0

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

(x - 2 ) (x + 71)

To summarize, since -2 and 71 multiply to -142 and add up 69, you know that the following is true:

x² + 69x - 142 = (x - 2 ) (x + 71)
