What two numbers multiply to -805 and add up to 108?

Here we answer the question: "What two numbers multiply to -805 and add up to 108?"

The answer to your question is:

-7 and 115

Below we illustrate and prove that -7 and 115 multiply to -805 and add up to 108:

-7 × 115 = -805
-7 + 115 = 108

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

x² + 108x - 805 = 0

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

(x - 7 ) (x + 115)

To summarize, since -7 and 115 multiply to -805 and add up 108, you know that the following is true:

x² + 108x - 805 = (x - 7 ) (x + 115)
