What two numbers multiply to -228 and add up to 7?

Here we answer the question: "What two numbers multiply to -228 and add up to 7?"

The answer to your question is:

-12 and 19

Below we illustrate and prove that -12 and 19 multiply to -228 and add up to 7:

-12 × 19 = -228
-12 + 19 = 7

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

x² + 7x - 228 = 0

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

(x - 12 ) (x + 19)

To summarize, since -12 and 19 multiply to -228 and add up 7, you know that the following is true:

x² + 7x - 228 = (x - 12 ) (x + 19)
