What two numbers multiply to 155 and add up to -156?

Here we answer the question: "What two numbers multiply to 155 and add up to -156?"

The answer to your question is:

-155 and -1

Below we illustrate and prove that -155 and -1 multiply to 155 and add up to -156:

-155 × -1 = 155
-155 + -1 = -156

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

x² - 156x + 155 = 0

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

(x - 155 ) (x - 1)

To summarize, since -155 and -1 multiply to 155 and add up -156, you know that the following is true:

x² - 156x + 155 = (x - 155 ) (x - 1)
