What two numbers multiply to 215 and add up to 48?

Here we answer the question: "What two numbers multiply to 215 and add up to 48?"

The answer to your question is:

5 and 43

Below we illustrate and prove that 5 and 43 multiply to 215 and add up to 48:

5 × 43 = 215
5 + 43 = 48

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

x² + 48x + 215 = 0

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

(x + 5 ) (x + 43)

To summarize, since 5 and 43 multiply to 215 and add up 48, you know that the following is true:

x² + 48x + 215 = (x + 5 ) (x + 43)
