Here we answer the question: "What two numbers multiply to -142 and add up to -69?"
The answer to your question is:
-71 and 2
Below we illustrate and prove that -71 and 2 multiply to -142 and add up to -69:
-71 × 2 = -142
-71 + 2 = -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 - 71 ) (x + 2)
To summarize, since -71 and 2 multiply to -142 and add up -69, you know that the following is true:
x2 - 69x - 142 = (x - 71 ) (x + 2)
