Here we answer the question: "What two numbers multiply to 768 and add up to 64?"
The answer to your question is:
16 and 48
Below we illustrate and prove that 16 and 48 multiply to 768 and add up to 64:
16 × 48 = 768
16 + 48 = 64
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 64x + 768 = 0
If so, the solution to factor the quadratic equation above is:
(x + 16 ) (x + 48)
To summarize, since 16 and 48 multiply to 768 and add up 64, you know that the following is true:
x2 + 64x + 768 = (x + 16 ) (x + 48)
