Here we answer the question: "What two numbers multiply to -264 and add up to -13?"
The answer to your question is:
-24 and 11
Below we illustrate and prove that -24 and 11 multiply to -264 and add up to -13:
-24 × 11 = -264
-24 + 11 = -13
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 13x - 264 = 0
If so, the solution to factor the quadratic equation above is:
(x - 24 ) (x + 11)
To summarize, since -24 and 11 multiply to -264 and add up -13, you know that the following is true:
x2 - 13x - 264 = (x - 24 ) (x + 11)
