Here we answer the question: "What two numbers multiply to 948 and add up to -91?"
The answer to your question is:
-79 and -12
Below we illustrate and prove that -79 and -12 multiply to 948 and add up to -91:
-79 × -12 = 948
-79 + -12 = -91
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 91x + 948 = 0
If so, the solution to factor the quadratic equation above is:
(x - 79 ) (x - 12)
To summarize, since -79 and -12 multiply to 948 and add up -91, you know that the following is true:
x2 - 91x + 948 = (x - 79 ) (x - 12)
