What two numbers multiply to 315 and add up to -108?

Here we answer the question: "What two numbers multiply to 315 and add up to -108?"

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 -108:

-105 × -3 = 315
-105 + -3 = -108

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

x² - 108x + 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 -108, you know that the following is true:

x² - 108x + 315 = (x - 105 ) (x - 3)
