What two numbers multiply to 660 and add up to -76?




Here we answer the question: "What two numbers multiply to 660 and add up to -76?"

The answer to your question is:

-66 and -10


Below we illustrate and prove that -66 and -10 multiply to 660 and add up to -76:

-66 × -10 = 660
-66 + -10 = -76

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

x2 - 76x + 660 = 0

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

(x - 66 ) (x - 10)

To summarize, since -66 and -10 multiply to 660 and add up -76, you know that the following is true:

x2 - 76x + 660 = (x - 66 ) (x - 10)
