What two numbers multiply to 158 and add up to -81?

Here we answer the question: "What two numbers multiply to 158 and add up to -81?"

The answer to your question is:

-79 and -2

Below we illustrate and prove that -79 and -2 multiply to 158 and add up to -81:

-79 × -2 = 158
-79 + -2 = -81

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

x² - 81x + 158 = 0

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

(x - 79 ) (x - 2)

To summarize, since -79 and -2 multiply to 158 and add up -81, you know that the following is true:

x² - 81x + 158 = (x - 79 ) (x - 2)
