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:

-7 and 35

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

-7 × 35 = -245
-7 + 35 = 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 - 7 ) (x + 35)

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

x² + 28x - 245 = (x - 7 ) (x + 35)
