Here we answer the question: "What two numbers multiply to 880 and add up to 71?"
The answer to your question is:
16 and 55
Below we illustrate and prove that 16 and 55 multiply to 880 and add up to 71:
16 × 55 = 880
16 + 55 = 71
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 71x + 880 = 0
If so, the solution to factor the quadratic equation above is:
(x + 16 ) (x + 55)
To summarize, since 16 and 55 multiply to 880 and add up 71, you know that the following is true:
x2 + 71x + 880 = (x + 16 ) (x + 55)
