Here we answer the question: "What two numbers multiply to -210 and add up to 37?"
The answer to your question is:
-5 and 42
Below we illustrate and prove that -5 and 42 multiply to -210 and add up to 37:
-5 × 42 = -210
-5 + 42 = 37
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 37x - 210 = 0
If so, the solution to factor the quadratic equation above is:
(x - 5 ) (x + 42)
To summarize, since -5 and 42 multiply to -210 and add up 37, you know that the following is true:
x2 + 37x - 210 = (x - 5 ) (x + 42)
