What two numbers multiply to -645 and add up to 28?




Here we answer the question: "What two numbers multiply to -645 and add up to 28?"

The answer to your question is:

-15 and 43


Below we illustrate and prove that -15 and 43 multiply to -645 and add up to 28:

-15 × 43 = -645
-15 + 43 = 28

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

x2 + 28x - 645 = 0

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

(x - 15 ) (x + 43)

To summarize, since -15 and 43 multiply to -645 and add up 28, you know that the following is true:

x2 + 28x - 645 = (x - 15 ) (x + 43)
