Here we answer the question: "What two numbers multiply to -553 and add up to 72?"
The answer to your question is:
-7 and 79
Below we illustrate and prove that -7 and 79 multiply to -553 and add up to 72:
-7 × 79 = -553
-7 + 79 = 72
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 72x - 553 = 0
If so, the solution to factor the quadratic equation above is:
(x - 7 ) (x + 79)
To summarize, since -7 and 79 multiply to -553 and add up 72, you know that the following is true:
x2 + 72x - 553 = (x - 7 ) (x + 79)
