What two numbers multiply to 880 and add up to -71?




Here we answer the question: "What two numbers multiply to 880 and add up to -71?"

The answer to your question is:

-55 and -16


Below we illustrate and prove that -55 and -16 multiply to 880 and add up to -71:

-55 × -16 = 880
-55 + -16 = -71

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

x2 - 71x + 880 = 0

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

(x - 55 ) (x - 16)

To summarize, since -55 and -16 multiply to 880 and add up -71, you know that the following is true:

x2 - 71x + 880 = (x - 55 ) (x - 16)
