What two numbers multiply to -178 and add up to 87?

Here we answer the question: "What two numbers multiply to -178 and add up to 87?"

The answer to your question is:

-2 and 89

Below we illustrate and prove that -2 and 89 multiply to -178 and add up to 87:

-2 × 89 = -178
-2 + 89 = 87

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

x² + 87x - 178 = 0

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

(x - 2 ) (x + 89)

To summarize, since -2 and 89 multiply to -178 and add up 87, you know that the following is true:

x² + 87x - 178 = (x - 2 ) (x + 89)
