What two numbers multiply to 84 and add up to -20?




Here we answer the question: "What two numbers multiply to 84 and add up to -20?"

The answer to your question is:

-14 and -6


Below we illustrate and prove that -14 and -6 multiply to 84 and add up to -20:

-14 × -6 = 84
-14 + -6 = -20

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

x2 - 20x + 84 = 0

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

(x - 14 ) (x - 6)

To summarize, since -14 and -6 multiply to 84 and add up -20, you know that the following is true:

x2 - 20x + 84 = (x - 14 ) (x - 6)
