What two numbers multiply to 195 and add up to -28?

Here we answer the question: "What two numbers multiply to 195 and add up to -28?"

The answer to your question is:

-15 and -13

Below we illustrate and prove that -15 and -13 multiply to 195 and add up to -28:

-15 × -13 = 195
-15 + -13 = -28

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

x² - 28x + 195 = 0

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

(x - 15 ) (x - 13)

To summarize, since -15 and -13 multiply to 195 and add up -28, you know that the following is true:

x² - 28x + 195 = (x - 15 ) (x - 13)
