What two numbers multiply to -210 and add up to -23?

Here we answer the question: "What two numbers multiply to -210 and add up to -23?"

The answer to your question is:

-30 and 7

Below we illustrate and prove that -30 and 7 multiply to -210 and add up to -23:

-30 × 7 = -210
-30 + 7 = -23

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

x² - 23x - 210 = 0

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

(x - 30 ) (x + 7)

To summarize, since -30 and 7 multiply to -210 and add up -23, you know that the following is true:

x² - 23x - 210 = (x - 30 ) (x + 7)
