What two numbers multiply to -210 and add up to 103?

Here we answer the question: "What two numbers multiply to -210 and add up to 103?"

The answer to your question is:

-2 and 105

Below we illustrate and prove that -2 and 105 multiply to -210 and add up to 103:

-2 × 105 = -210
-2 + 105 = 103

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

x² + 103x - 210 = 0

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

(x - 2 ) (x + 105)

To summarize, since -2 and 105 multiply to -210 and add up 103, you know that the following is true:

x² + 103x - 210 = (x - 2 ) (x + 105)
