What two numbers multiply to -648 and add up to -158?

Here we answer the question: "What two numbers multiply to -648 and add up to -158?"

The answer to your question is:

-162 and 4

Below we illustrate and prove that -162 and 4 multiply to -648 and add up to -158:

-162 × 4 = -648
-162 + 4 = -158

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

x² - 158x - 648 = 0

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

(x - 162 ) (x + 4)

To summarize, since -162 and 4 multiply to -648 and add up -158, you know that the following is true:

x² - 158x - 648 = (x - 162 ) (x + 4)
