What two numbers multiply to -235 and add up to 42?

Here we answer the question: "What two numbers multiply to -235 and add up to 42?"

The answer to your question is:

-5 and 47

Below we illustrate and prove that -5 and 47 multiply to -235 and add up to 42:

-5 × 47 = -235
-5 + 47 = 42

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² + 42x - 235 = 0

If so, the solution to factor the quadratic equation above is:

(x - 5 ) (x + 47)

To summarize, since -5 and 47 multiply to -235 and add up 42, you know that the following is true:

x² + 42x - 235 = (x - 5 ) (x + 47)
