What two numbers multiply to -477 and add up to 156?

Here we answer the question: "What two numbers multiply to -477 and add up to 156?"

The answer to your question is:

-3 and 159

Below we illustrate and prove that -3 and 159 multiply to -477 and add up to 156:

-3 × 159 = -477
-3 + 159 = 156

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

x² + 156x - 477 = 0

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

(x - 3 ) (x + 159)

To summarize, since -3 and 159 multiply to -477 and add up 156, you know that the following is true:

x² + 156x - 477 = (x - 3 ) (x + 159)
