Here we answer the question: "What two numbers multiply to 512 and add up to 48?"
The answer to your question is:
16 and 32
Below we illustrate and prove that 16 and 32 multiply to 512 and add up to 48:
16 × 32 = 512
16 + 32 = 48
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 48x + 512 = 0
If so, the solution to factor the quadratic equation above is:
(x + 16 ) (x + 32)
To summarize, since 16 and 32 multiply to 512 and add up 48, you know that the following is true:
x2 + 48x + 512 = (x + 16 ) (x + 32)
