Here we answer the question: "What two numbers multiply to 462 and add up to -157?"
The answer to your question is:
-154 and -3
Below we illustrate and prove that -154 and -3 multiply to 462 and add up to -157:
-154 × -3 = 462
-154 + -3 = -157
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 157x + 462 = 0
If so, the solution to factor the quadratic equation above is:
(x - 154 ) (x - 3)
To summarize, since -154 and -3 multiply to 462 and add up -157, you know that the following is true:
x2 - 157x + 462 = (x - 154 ) (x - 3)
