Here we answer the question: "What two numbers multiply to 824 and add up to -210?"
The answer to your question is:
-206 and -4
Below we illustrate and prove that -206 and -4 multiply to 824 and add up to -210:
-206 × -4 = 824
-206 + -4 = -210
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 210x + 824 = 0
If so, the solution to factor the quadratic equation above is:
(x - 206 ) (x - 4)
To summarize, since -206 and -4 multiply to 824 and add up -210, you know that the following is true:
x2 - 210x + 824 = (x - 206 ) (x - 4)
