Here we answer the question: "What two numbers multiply to -785 and add up to -152?"
The answer to your question is:
-157 and 5
Below we illustrate and prove that -157 and 5 multiply to -785 and add up to -152:
-157 × 5 = -785
-157 + 5 = -152
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 152x - 785 = 0
If so, the solution to factor the quadratic equation above is:
(x - 157 ) (x + 5)
To summarize, since -157 and 5 multiply to -785 and add up -152, you know that the following is true:
x2 - 152x - 785 = (x - 157 ) (x + 5)
