Here we answer the question: "What two numbers multiply to 30 and add up to -17?"
The answer to your question is:
-15 and -2
Below we illustrate and prove that -15 and -2 multiply to 30 and add up to -17:
-15 × -2 = 30
-15 + -2 = -17
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 17x + 30 = 0
If so, the solution to factor the quadratic equation above is:
(x - 15 ) (x - 2)
To summarize, since -15 and -2 multiply to 30 and add up -17, you know that the following is true:
x2 - 17x + 30 = (x - 15 ) (x - 2)
