What two numbers multiply to -103 and add up to 102?

Here we answer the question: "What two numbers multiply to -103 and add up to 102?"

The answer to your question is:

-1 and 103

Below we illustrate and prove that -1 and 103 multiply to -103 and add up to 102:

-1 × 103 = -103
-1 + 103 = 102

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

x² + 102x - 103 = 0

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

(x - 1 ) (x + 103)

To summarize, since -1 and 103 multiply to -103 and add up 102, you know that the following is true:

x² + 102x - 103 = (x - 1 ) (x + 103)
