Here we answer the question: "What two numbers multiply to 507 and add up to 52?"
The answer to your question is:
13 and 39
Below we illustrate and prove that 13 and 39 multiply to 507 and add up to 52:
13 × 39 = 507
13 + 39 = 52
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 52x + 507 = 0
If so, the solution to factor the quadratic equation above is:
(x + 13 ) (x + 39)
To summarize, since 13 and 39 multiply to 507 and add up 52, you know that the following is true:
x2 + 52x + 507 = (x + 13 ) (x + 39)
