Here we answer the question: "What two numbers multiply to -286 and add up to 15?"
The answer to your question is:
-11 and 26
Below we illustrate and prove that -11 and 26 multiply to -286 and add up to 15:
-11 × 26 = -286
-11 + 26 = 15
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 15x - 286 = 0
If so, the solution to factor the quadratic equation above is:
(x - 11 ) (x + 26)
To summarize, since -11 and 26 multiply to -286 and add up 15, you know that the following is true:
x2 + 15x - 286 = (x - 11 ) (x + 26)
