Here we answer the question: "What two numbers multiply to 580 and add up to -149?"
The answer to your question is:
-145 and -4
Below we illustrate and prove that -145 and -4 multiply to 580 and add up to -149:
-145 × -4 = 580
-145 + -4 = -149
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 149x + 580 = 0
If so, the solution to factor the quadratic equation above is:
(x - 145 ) (x - 4)
To summarize, since -145 and -4 multiply to 580 and add up -149, you know that the following is true:
x2 - 149x + 580 = (x - 145 ) (x - 4)
