What two numbers multiply to 216 and add up to 30?




Here we answer the question: "What two numbers multiply to 216 and add up to 30?"

The answer to your question is:

12 and 18


Below we illustrate and prove that 12 and 18 multiply to 216 and add up to 30:

12 × 18 = 216
12 + 18 = 30

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

x2 + 30x + 216 = 0

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

(x + 12 ) (x + 18)

To summarize, since 12 and 18 multiply to 216 and add up 30, you know that the following is true:

x2 + 30x + 216 = (x + 12 ) (x + 18)
