Here we answer the question: "What two numbers multiply to 840 and add up to 283?"
The answer to your question is:
3 and 280
Below we illustrate and prove that 3 and 280 multiply to 840 and add up to 283:
3 × 280 = 840
3 + 280 = 283
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 283x + 840 = 0
If so, the solution to factor the quadratic equation above is:
(x + 3 ) (x + 280)
To summarize, since 3 and 280 multiply to 840 and add up 283, you know that the following is true:
x2 + 283x + 840 = (x + 3 ) (x + 280)
