Here we answer the question: "What two numbers multiply to 915 and add up to 76?"
The answer to your question is:
15 and 61
Below we illustrate and prove that 15 and 61 multiply to 915 and add up to 76:
15 × 61 = 915
15 + 61 = 76
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 76x + 915 = 0
If so, the solution to factor the quadratic equation above is:
(x + 15 ) (x + 61)
To summarize, since 15 and 61 multiply to 915 and add up 76, you know that the following is true:
x2 + 76x + 915 = (x + 15 ) (x + 61)
