Here we answer the question: "What two numbers multiply to 243 and add up to -36?"
The answer to your question is:
-27 and -9
Below we illustrate and prove that -27 and -9 multiply to 243 and add up to -36:
-27 × -9 = 243
-27 + -9 = -36
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 36x + 243 = 0
If so, the solution to factor the quadratic equation above is:
(x - 27 ) (x - 9)
To summarize, since -27 and -9 multiply to 243 and add up -36, you know that the following is true:
x2 - 36x + 243 = (x - 27 ) (x - 9)
