What two numbers multiply to -189 and add up to 188?

Here we answer the question: "What two numbers multiply to -189 and add up to 188?"

The answer to your question is:

-1 and 189

Below we illustrate and prove that -1 and 189 multiply to -189 and add up to 188:

-1 × 189 = -189
-1 + 189 = 188

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

x² + 188x - 189 = 0

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

(x - 1 ) (x + 189)

To summarize, since -1 and 189 multiply to -189 and add up 188, you know that the following is true:

x² + 188x - 189 = (x - 1 ) (x + 189)
