Here we answer the question: "What two numbers multiply to -775 and add up to -150?"
The answer to your question is:
-155 and 5
Below we illustrate and prove that -155 and 5 multiply to -775 and add up to -150:
-155 × 5 = -775
-155 + 5 = -150
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 150x - 775 = 0
If so, the solution to factor the quadratic equation above is:
(x - 155 ) (x + 5)
To summarize, since -155 and 5 multiply to -775 and add up -150, you know that the following is true:
x2 - 150x - 775 = (x - 155 ) (x + 5)
