What two numbers multiply to -72 and add up to -1?




Here we answer the question: "What two numbers multiply to -72 and add up to -1?"

The answer to your question is:

-9 and 8


Below we illustrate and prove that -9 and 8 multiply to -72 and add up to -1:

-9 × 8 = -72
-9 + 8 = -1

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

x2 - 1x - 72 = 0

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

(x - 9 ) (x + 8)

To summarize, since -9 and 8 multiply to -72 and add up -1, you know that the following is true:

x2 - 1x - 72 = (x - 9 ) (x + 8)
