What two numbers multiply to -990 and add up to 159?

Here we answer the question: "What two numbers multiply to -990 and add up to 159?"

The answer to your question is:

-6 and 165

Below we illustrate and prove that -6 and 165 multiply to -990 and add up to 159:

-6 × 165 = -990
-6 + 165 = 159

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

x² + 159x - 990 = 0

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

(x - 6 ) (x + 165)

To summarize, since -6 and 165 multiply to -990 and add up 159, you know that the following is true:

x² + 159x - 990 = (x - 6 ) (x + 165)
