Here we answer the question: "What two numbers multiply to 240 and add up to 38?"
The answer to your question is:
8 and 30
Below we illustrate and prove that 8 and 30 multiply to 240 and add up to 38:
8 × 30 = 240
8 + 30 = 38
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 38x + 240 = 0
If so, the solution to factor the quadratic equation above is:
(x + 8 ) (x + 30)
To summarize, since 8 and 30 multiply to 240 and add up 38, you know that the following is true:
x2 + 38x + 240 = (x + 8 ) (x + 30)
