What two numbers multiply to -158 and add up to -77?

Here we answer the question: "What two numbers multiply to -158 and add up to -77?"

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 -77:

-79 × 2 = -158
-79 + 2 = -77

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

x² - 77x - 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 -77, you know that the following is true:

x² - 77x - 158 = (x - 79 ) (x + 2)
