Here we answer the question: "What two numbers multiply to 38 and add up to 39?"
The answer to your question is:
1 and 38
Below we illustrate and prove that 1 and 38 multiply to 38 and add up to 39:
1 × 38 = 38
1 + 38 = 39
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 39x + 38 = 0
If so, the solution to factor the quadratic equation above is:
(x + 1 ) (x + 38)
To summarize, since 1 and 38 multiply to 38 and add up 39, you know that the following is true:
x2 + 39x + 38 = (x + 1 ) (x + 38)
