What two numbers multiply to -178 and add up to 177?

Here we answer the question: "What two numbers multiply to -178 and add up to 177?"

The answer to your question is:

-1 and 178

Below we illustrate and prove that -1 and 178 multiply to -178 and add up to 177:

-1 × 178 = -178
-1 + 178 = 177

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

x² + 177x - 178 = 0

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

(x - 1 ) (x + 178)

To summarize, since -1 and 178 multiply to -178 and add up 177, you know that the following is true:

x² + 177x - 178 = (x - 1 ) (x + 178)
