What two numbers multiply to -315 and add up to -102?

Here we answer the question: "What two numbers multiply to -315 and add up to -102?"

The answer to your question is:

-105 and 3

Below we illustrate and prove that -105 and 3 multiply to -315 and add up to -102:

-105 × 3 = -315
-105 + 3 = -102

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

x² - 102x - 315 = 0

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

(x - 105 ) (x + 3)

To summarize, since -105 and 3 multiply to -315 and add up -102, you know that the following is true:

x² - 102x - 315 = (x - 105 ) (x + 3)
