What two numbers multiply to -356 and add up to -85?

Here we answer the question: "What two numbers multiply to -356 and add up to -85?"

The answer to your question is:

-89 and 4

Below we illustrate and prove that -89 and 4 multiply to -356 and add up to -85:

-89 × 4 = -356
-89 + 4 = -85

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

x² - 85x - 356 = 0

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

(x - 89 ) (x + 4)

To summarize, since -89 and 4 multiply to -356 and add up -85, you know that the following is true:

x² - 85x - 356 = (x - 89 ) (x + 4)
