Here we answer the question: "What two numbers multiply to 474 and add up to -161?"
The answer to your question is:
-158 and -3
Below we illustrate and prove that -158 and -3 multiply to 474 and add up to -161:
-158 × -3 = 474
-158 + -3 = -161
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 161x + 474 = 0
If so, the solution to factor the quadratic equation above is:
(x - 158 ) (x - 3)
To summarize, since -158 and -3 multiply to 474 and add up -161, you know that the following is true:
x2 - 161x + 474 = (x - 158 ) (x - 3)
