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:

-4 and 89

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

-4 × 89 = -356
-4 + 89 = 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 - 4 ) (x + 89)

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

x² + 85x - 356 = (x - 4 ) (x + 89)
