What two numbers multiply to -210 and add up to 1?

Here we answer the question: "What two numbers multiply to -210 and add up to 1?"

The answer to your question is:

-14 and 15

Below we illustrate and prove that -14 and 15 multiply to -210 and add up to 1:

-14 × 15 = -210
-14 + 15 = 1

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

x² + 1x - 210 = 0

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

(x - 14 ) (x + 15)

To summarize, since -14 and 15 multiply to -210 and add up 1, you know that the following is true:

x² + 1x - 210 = (x - 14 ) (x + 15)
