What two numbers multiply to -345 and add up to 112?

Here we answer the question: "What two numbers multiply to -345 and add up to 112?"

The answer to your question is:

-3 and 115

Below we illustrate and prove that -3 and 115 multiply to -345 and add up to 112:

-3 × 115 = -345
-3 + 115 = 112

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

x² + 112x - 345 = 0

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

(x - 3 ) (x + 115)

To summarize, since -3 and 115 multiply to -345 and add up 112, you know that the following is true:

x² + 112x - 345 = (x - 3 ) (x + 115)
