What two numbers multiply to 65 and add up to 18?

Here we answer the question: "What two numbers multiply to 65 and add up to 18?"

The answer to your question is:

5 and 13

Below we illustrate and prove that 5 and 13 multiply to 65 and add up to 18:

5 × 13 = 65
5 + 13 = 18

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

x² + 18x + 65 = 0

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

(x + 5 ) (x + 13)

To summarize, since 5 and 13 multiply to 65 and add up 18, you know that the following is true:

x² + 18x + 65 = (x + 5 ) (x + 13)
