What two numbers multiply to -245 and add up to -28?

Here we answer the question: "What two numbers multiply to -245 and add up to -28?"

The answer to your question is:

-35 and 7

Below we illustrate and prove that -35 and 7 multiply to -245 and add up to -28:

-35 × 7 = -245
-35 + 7 = -28

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

x² - 28x - 245 = 0

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

(x - 35 ) (x + 7)

To summarize, since -35 and 7 multiply to -245 and add up -28, you know that the following is true:

x² - 28x - 245 = (x - 35 ) (x + 7)
