What two numbers multiply to 231 and add up to 40?

Here we answer the question: "What two numbers multiply to 231 and add up to 40?"

The answer to your question is:

7 and 33

Below we illustrate and prove that 7 and 33 multiply to 231 and add up to 40:

7 × 33 = 231
7 + 33 = 40

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

x² + 40x + 231 = 0

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

(x + 7 ) (x + 33)

To summarize, since 7 and 33 multiply to 231 and add up 40, you know that the following is true:

x² + 40x + 231 = (x + 7 ) (x + 33)
