What two numbers multiply to -561 and add up to 16?




Here we answer the question: "What two numbers multiply to -561 and add up to 16?"

The answer to your question is:

-17 and 33


Below we illustrate and prove that -17 and 33 multiply to -561 and add up to 16:

-17 × 33 = -561
-17 + 33 = 16

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

x2 + 16x - 561 = 0

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

(x - 17 ) (x + 33)

To summarize, since -17 and 33 multiply to -561 and add up 16, you know that the following is true:

x2 + 16x - 561 = (x - 17 ) (x + 33)
