Here we answer the question: "What two numbers multiply to -210 and add up to -37?"
The answer to your question is:
-42 and 5
Below we illustrate and prove that -42 and 5 multiply to -210 and add up to -37:
-42 × 5 = -210
-42 + 5 = -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 - 42 ) (x + 5)
To summarize, since -42 and 5 multiply to -210 and add up -37, you know that the following is true:
x2 - 37x - 210 = (x - 42 ) (x + 5)
