What two numbers multiply to -196 and add up to -45?

Here we answer the question: "What two numbers multiply to -196 and add up to -45?"

The answer to your question is:

-49 and 4

Below we illustrate and prove that -49 and 4 multiply to -196 and add up to -45:

-49 × 4 = -196
-49 + 4 = -45

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

x² - 45x - 196 = 0

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

(x - 49 ) (x + 4)

To summarize, since -49 and 4 multiply to -196 and add up -45, you know that the following is true:

x² - 45x - 196 = (x - 49 ) (x + 4)
