What two numbers multiply to -220 and add up to 12?




Here we answer the question: "What two numbers multiply to -220 and add up to 12?"

The answer to your question is:

-10 and 22


Below we illustrate and prove that -10 and 22 multiply to -220 and add up to 12:

-10 × 22 = -220
-10 + 22 = 12

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

x2 + 12x - 220 = 0

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

(x - 10 ) (x + 22)

To summarize, since -10 and 22 multiply to -220 and add up 12, you know that the following is true:

x2 + 12x - 220 = (x - 10 ) (x + 22)
