Here we answer the question: "What two numbers multiply to -893 and add up to -28?"
The answer to your question is:
-47 and 19
Below we illustrate and prove that -47 and 19 multiply to -893 and add up to -28:
-47 × 19 = -893
-47 + 19 = -28
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 28x - 893 = 0
If so, the solution to factor the quadratic equation above is:
(x - 47 ) (x + 19)
To summarize, since -47 and 19 multiply to -893 and add up -28, you know that the following is true:
x2 - 28x - 893 = (x - 47 ) (x + 19)
