What two numbers multiply to 155 and add up to -36?

Here we answer the question: "What two numbers multiply to 155 and add up to -36?"

The answer to your question is:

-31 and -5

Below we illustrate and prove that -31 and -5 multiply to 155 and add up to -36:

-31 × -5 = 155
-31 + -5 = -36

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

x² - 36x + 155 = 0

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

(x - 31 ) (x - 5)

To summarize, since -31 and -5 multiply to 155 and add up -36, you know that the following is true:

x² - 36x + 155 = (x - 31 ) (x - 5)
