What two numbers multiply to 720 and add up to -58?




Here we answer the question: "What two numbers multiply to 720 and add up to -58?"

The answer to your question is:

-40 and -18


Below we illustrate and prove that -40 and -18 multiply to 720 and add up to -58:

-40 × -18 = 720
-40 + -18 = -58

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

x2 - 58x + 720 = 0

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

(x - 40 ) (x - 18)

To summarize, since -40 and -18 multiply to 720 and add up -58, you know that the following is true:

x2 - 58x + 720 = (x - 40 ) (x - 18)
