What two numbers multiply to 36 and add up to -15?

Here we answer the question: "What two numbers multiply to 36 and add up to -15?"

The answer to your question is:

-12 and -3

Below we illustrate and prove that -12 and -3 multiply to 36 and add up to -15:

-12 × -3 = 36
-12 + -3 = -15

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

x² - 15x + 36 = 0

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

(x - 12 ) (x - 3)

To summarize, since -12 and -3 multiply to 36 and add up -15, you know that the following is true:

x² - 15x + 36 = (x - 12 ) (x - 3)
