What two numbers multiply to 178 and add up to -91?

Here we answer the question: "What two numbers multiply to 178 and add up to -91?"

The answer to your question is:

-89 and -2

Below we illustrate and prove that -89 and -2 multiply to 178 and add up to -91:

-89 × -2 = 178
-89 + -2 = -91

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

x² - 91x + 178 = 0

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

(x - 89 ) (x - 2)

To summarize, since -89 and -2 multiply to 178 and add up -91, you know that the following is true:

x² - 91x + 178 = (x - 89 ) (x - 2)
