Here we answer the question: "What two numbers multiply to 300 and add up to -65?"
The answer to your question is:
-60 and -5
Below we illustrate and prove that -60 and -5 multiply to 300 and add up to -65:
-60 × -5 = 300
-60 + -5 = -65
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 65x + 300 = 0
If so, the solution to factor the quadratic equation above is:
(x - 60 ) (x - 5)
To summarize, since -60 and -5 multiply to 300 and add up -65, you know that the following is true:
x2 - 65x + 300 = (x - 60 ) (x - 5)
