What two numbers multiply to -73 and add up to 72?




Here we answer the question: "What two numbers multiply to -73 and add up to 72?"

The answer to your question is:

-1 and 73


Below we illustrate and prove that -1 and 73 multiply to -73 and add up to 72:

-1 × 73 = -73
-1 + 73 = 72

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

x2 + 72x - 73 = 0

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

(x - 1 ) (x + 73)

To summarize, since -1 and 73 multiply to -73 and add up 72, you know that the following is true:

x2 + 72x - 73 = (x - 1 ) (x + 73)
