Here we answer the question: "What two numbers multiply to 280 and add up to -74?"
The answer to your question is:
-70 and -4
Below we illustrate and prove that -70 and -4 multiply to 280 and add up to -74:
-70 × -4 = 280
-70 + -4 = -74
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 74x + 280 = 0
If so, the solution to factor the quadratic equation above is:
(x - 70 ) (x - 4)
To summarize, since -70 and -4 multiply to 280 and add up -74, you know that the following is true:
x2 - 74x + 280 = (x - 70 ) (x - 4)
