Here we answer the question: "What two numbers multiply to 60 and add up to 19?"
The answer to your question is:
4 and 15
Below we illustrate and prove that 4 and 15 multiply to 60 and add up to 19:
4 × 15 = 60
4 + 15 = 19
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 19x + 60 = 0
If so, the solution to factor the quadratic equation above is:
(x + 4 ) (x + 15)
To summarize, since 4 and 15 multiply to 60 and add up 19, you know that the following is true:
x2 + 19x + 60 = (x + 4 ) (x + 15)
