Here we answer the question: "What two numbers multiply to -216 and add up to 19?"
The answer to your question is:
-8 and 27
Below we illustrate and prove that -8 and 27 multiply to -216 and add up to 19:
-8 × 27 = -216
-8 + 27 = 19
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 19x - 216 = 0
If so, the solution to factor the quadratic equation above is:
(x - 8 ) (x + 27)
To summarize, since -8 and 27 multiply to -216 and add up 19, you know that the following is true:
x2 + 19x - 216 = (x - 8 ) (x + 27)
