Here we answer the question: "What two numbers multiply to 876 and add up to -85?"
The answer to your question is:
-73 and -12
Below we illustrate and prove that -73 and -12 multiply to 876 and add up to -85:
-73 × -12 = 876
-73 + -12 = -85
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 85x + 876 = 0
If so, the solution to factor the quadratic equation above is:
(x - 73 ) (x - 12)
To summarize, since -73 and -12 multiply to 876 and add up -85, you know that the following is true:
x2 - 85x + 876 = (x - 73 ) (x - 12)
