What two numbers multiply to 450 and add up to 45?

Here we answer the question: "What two numbers multiply to 450 and add up to 45?"

The answer to your question is:

15 and 30

Below we illustrate and prove that 15 and 30 multiply to 450 and add up to 45:

15 × 30 = 450
15 + 30 = 45

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

x² + 45x + 450 = 0

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

(x + 15 ) (x + 30)

To summarize, since 15 and 30 multiply to 450 and add up 45, you know that the following is true:

x² + 45x + 450 = (x + 15 ) (x + 30)
