Answer:
Here we answer the question: "What two numbers multiply to -36 and add up to -16?"
The answer to your question is:
2 and -18
Step-by-step explanation: 2 x -18 = -36
2 + (-18) = -16
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 16x - 36 = 0
If so, the solution to factor the quadratic equation above is:
(X + 2 ) (X - 18)
To summarize, since 2 and -18 multiply to -36 and add up -16, you know that the following is true:
x2 - 16x - 36 = (X + 2 ) (X - 18)
