Here we answer the question: "What two numbers multiply to -533 and add up to 28?"
The answer to your question is:
-13 and 41
Below we illustrate and prove that -13 and 41 multiply to -533 and add up to 28:
-13 × 41 = -533
-13 + 41 = 28
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 28x - 533 = 0
If so, the solution to factor the quadratic equation above is:
(x - 13 ) (x + 41)
To summarize, since -13 and 41 multiply to -533 and add up 28, you know that the following is true:
x2 + 28x - 533 = (x - 13 ) (x + 41)
