What two numbers multiply to -315 and add up to -38?

Here we answer the question: "What two numbers multiply to -315 and add up to -38?"

The answer to your question is:

-45 and 7

Below we illustrate and prove that -45 and 7 multiply to -315 and add up to -38:

-45 × 7 = -315
-45 + 7 = -38

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

x² - 38x - 315 = 0

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

(x - 45 ) (x + 7)

To summarize, since -45 and 7 multiply to -315 and add up -38, you know that the following is true:

x² - 38x - 315 = (x - 45 ) (x + 7)
