What two numbers multiply to 880 and add up to -91?




Here we answer the question: "What two numbers multiply to 880 and add up to -91?"

The answer to your question is:

-80 and -11


Below we illustrate and prove that -80 and -11 multiply to 880 and add up to -91:

-80 × -11 = 880
-80 + -11 = -91

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

x2 - 91x + 880 = 0

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

(x - 80 ) (x - 11)

To summarize, since -80 and -11 multiply to 880 and add up -91, you know that the following is true:

x2 - 91x + 880 = (x - 80 ) (x - 11)
