What two numbers multiply to 315 and add up to -36?

Here we answer the question: "What two numbers multiply to 315 and add up to -36?"

The answer to your question is:

-21 and -15

Below we illustrate and prove that -21 and -15 multiply to 315 and add up to -36:

-21 × -15 = 315
-21 + -15 = -36

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

x² - 36x + 315 = 0

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

(x - 21 ) (x - 15)

To summarize, since -21 and -15 multiply to 315 and add up -36, you know that the following is true:

x² - 36x + 315 = (x - 21 ) (x - 15)
