What two numbers multiply to -228 and add up to 53?




Here we answer the question: "What two numbers multiply to -228 and add up to 53?"

The answer to your question is:

-4 and 57


Below we illustrate and prove that -4 and 57 multiply to -228 and add up to 53:

-4 × 57 = -228
-4 + 57 = 53

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

x2 + 53x - 228 = 0

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

(x - 4 ) (x + 57)

To summarize, since -4 and 57 multiply to -228 and add up 53, you know that the following is true:

x2 + 53x - 228 = (x - 4 ) (x + 57)
