What two numbers multiply to -820 and add up to -159?

Here we answer the question: "What two numbers multiply to -820 and add up to -159?"

The answer to your question is:

-164 and 5

Below we illustrate and prove that -164 and 5 multiply to -820 and add up to -159:

-164 × 5 = -820
-164 + 5 = -159

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

x² - 159x - 820 = 0

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

(x - 164 ) (x + 5)

To summarize, since -164 and 5 multiply to -820 and add up -159, you know that the following is true:

x² - 159x - 820 = (x - 164 ) (x + 5)
