Here we answer the question: "What two numbers multiply to -161 and add up to -16?"
The answer to your question is:
-23 and 7
Below we illustrate and prove that -23 and 7 multiply to -161 and add up to -16:
-23 × 7 = -161
-23 + 7 = -16
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 16x - 161 = 0
If so, the solution to factor the quadratic equation above is:
(x - 23 ) (x + 7)
To summarize, since -23 and 7 multiply to -161 and add up -16, you know that the following is true:
x2 - 16x - 161 = (x - 23 ) (x + 7)
