Here we answer the question: "What two numbers multiply to -30 and add up to 29?"
The answer to your question is:
-1 and 30
Below we illustrate and prove that -1 and 30 multiply to -30 and add up to 29:
-1 × 30 = -30
-1 + 30 = 29
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 29x - 30 = 0
If so, the solution to factor the quadratic equation above is:
(x - 1 ) (x + 30)
To summarize, since -1 and 30 multiply to -30 and add up 29, you know that the following is true:
x2 + 29x - 30 = (x - 1 ) (x + 30)
