Here we answer the question: "What two numbers multiply to 488 and add up to -69?"
The answer to your question is:
-61 and -8
Below we illustrate and prove that -61 and -8 multiply to 488 and add up to -69:
-61 × -8 = 488
-61 + -8 = -69
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 69x + 488 = 0
If so, the solution to factor the quadratic equation above is:
(x - 61 ) (x - 8)
To summarize, since -61 and -8 multiply to 488 and add up -69, you know that the following is true:
x2 - 69x + 488 = (x - 61 ) (x - 8)
