Here we answer the question: "What two numbers multiply to 180 and add up to -28?"
The answer to your question is:
-18 and -10
Below we illustrate and prove that -18 and -10 multiply to 180 and add up to -28:
-18 × -10 = 180
-18 + -10 = -28
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 28x + 180 = 0
If so, the solution to factor the quadratic equation above is:
(x - 18 ) (x - 10)
To summarize, since -18 and -10 multiply to 180 and add up -28, you know that the following is true:
x2 - 28x + 180 = (x - 18 ) (x - 10)
