What two numbers multiply to 308 and add up to -156?

Here we answer the question: "What two numbers multiply to 308 and add up to -156?"

The answer to your question is:

-154 and -2

Below we illustrate and prove that -154 and -2 multiply to 308 and add up to -156:

-154 × -2 = 308
-154 + -2 = -156

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

x² - 156x + 308 = 0

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

(x - 154 ) (x - 2)

To summarize, since -154 and -2 multiply to 308 and add up -156, you know that the following is true:

x² - 156x + 308 = (x - 154 ) (x - 2)
