Here we answer the question: "What two numbers multiply to 972 and add up to -93?"
The answer to your question is:
-81 and -12
Below we illustrate and prove that -81 and -12 multiply to 972 and add up to -93:
-81 × -12 = 972
-81 + -12 = -93
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 93x + 972 = 0
If so, the solution to factor the quadratic equation above is:
(x - 81 ) (x - 12)
To summarize, since -81 and -12 multiply to 972 and add up -93, you know that the following is true:
x2 - 93x + 972 = (x - 81 ) (x - 12)
