What two numbers multiply to -380 and add up to 91?

Here we answer the question: "What two numbers multiply to -380 and add up to 91?"

The answer to your question is:

-4 and 95

Below we illustrate and prove that -4 and 95 multiply to -380 and add up to 91:

-4 × 95 = -380
-4 + 95 = 91

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

x² + 91x - 380 = 0

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

(x - 4 ) (x + 95)

To summarize, since -4 and 95 multiply to -380 and add up 91, you know that the following is true:

x² + 91x - 380 = (x - 4 ) (x + 95)
