What two numbers multiply to 840 and add up to -71?




Here we answer the question: "What two numbers multiply to 840 and add up to -71?"

The answer to your question is:

-56 and -15


Below we illustrate and prove that -56 and -15 multiply to 840 and add up to -71:

-56 × -15 = 840
-56 + -15 = -71

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

x2 - 71x + 840 = 0

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

(x - 56 ) (x - 15)

To summarize, since -56 and -15 multiply to 840 and add up -71, you know that the following is true:

x2 - 71x + 840 = (x - 56 ) (x - 15)
