Here we answer the question: "What two numbers multiply to -810 and add up to -3?"
The answer to your question is:
-30 and 27
Below we illustrate and prove that -30 and 27 multiply to -810 and add up to -3:
-30 × 27 = -810
-30 + 27 = -3
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 3x - 810 = 0
If so, the solution to factor the quadratic equation above is:
(x - 30 ) (x + 27)
To summarize, since -30 and 27 multiply to -810 and add up -3, you know that the following is true:
x2 - 3x - 810 = (x - 30 ) (x + 27)
