What two numbers multiply to -66 and add up to -19?




Here we answer the question: "What two numbers multiply to -66 and add up to -19?"

The answer to your question is:

-22 and 3


Below we illustrate and prove that -22 and 3 multiply to -66 and add up to -19:

-22 × 3 = -66
-22 + 3 = -19

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

x2 - 19x - 66 = 0

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

(x - 22 ) (x + 3)

To summarize, since -22 and 3 multiply to -66 and add up -19, you know that the following is true:

x2 - 19x - 66 = (x - 22 ) (x + 3)
