What two numbers multiply to -318 and add up to 103?

Here we answer the question: "What two numbers multiply to -318 and add up to 103?"

The answer to your question is:

-3 and 106

Below we illustrate and prove that -3 and 106 multiply to -318 and add up to 103:

-3 × 106 = -318
-3 + 106 = 103

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

x² + 103x - 318 = 0

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

(x - 3 ) (x + 106)

To summarize, since -3 and 106 multiply to -318 and add up 103, you know that the following is true:

x² + 103x - 318 = (x - 3 ) (x + 106)
