What two numbers multiply to 80 and add up to 24?




Here we answer the question: "What two numbers multiply to 80 and add up to 24?"

The answer to your question is:

4 and 20


Below we illustrate and prove that 4 and 20 multiply to 80 and add up to 24:

4 × 20 = 80
4 + 20 = 24

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

x2 + 24x + 80 = 0

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

(x + 4 ) (x + 20)

To summarize, since 4 and 20 multiply to 80 and add up 24, you know that the following is true:

x2 + 24x + 80 = (x + 4 ) (x + 20)
