What two numbers multiply to 855 and add up to -72?




Here we answer the question: "What two numbers multiply to 855 and add up to -72?"

The answer to your question is:

-57 and -15


Below we illustrate and prove that -57 and -15 multiply to 855 and add up to -72:

-57 × -15 = 855
-57 + -15 = -72

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

x2 - 72x + 855 = 0

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

(x - 57 ) (x - 15)

To summarize, since -57 and -15 multiply to 855 and add up -72, you know that the following is true:

x2 - 72x + 855 = (x - 57 ) (x - 15)
