What two numbers multiply to 189 and add up to 30?

Here we answer the question: "What two numbers multiply to 189 and add up to 30?"

The answer to your question is:

9 and 21

Below we illustrate and prove that 9 and 21 multiply to 189 and add up to 30:

9 × 21 = 189
9 + 21 = 30

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

x² + 30x + 189 = 0

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

(x + 9 ) (x + 21)

To summarize, since 9 and 21 multiply to 189 and add up 30, you know that the following is true:

x² + 30x + 189 = (x + 9 ) (x + 21)
