Here we answer the question: "What two numbers multiply to 880 and add up to -98?"
The answer to your question is:
-88 and -10
Below we illustrate and prove that -88 and -10 multiply to 880 and add up to -98:
-88 × -10 = 880
-88 + -10 = -98
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 98x + 880 = 0
If so, the solution to factor the quadratic equation above is:
(x - 88 ) (x - 10)
To summarize, since -88 and -10 multiply to 880 and add up -98, you know that the following is true:
x2 - 98x + 880 = (x - 88 ) (x - 10)
