What two numbers multiply to 615 and add up to -208?

Here we answer the question: "What two numbers multiply to 615 and add up to -208?"

The answer to your question is:

-205 and -3

Below we illustrate and prove that -205 and -3 multiply to 615 and add up to -208:

-205 × -3 = 615
-205 + -3 = -208

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

x² - 208x + 615 = 0

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

(x - 205 ) (x - 3)

To summarize, since -205 and -3 multiply to 615 and add up -208, you know that the following is true:

x² - 208x + 615 = (x - 205 ) (x - 3)
