What two numbers multiply to 27 and add up to 28?

Here we answer the question: "What two numbers multiply to 27 and add up to 28?"

The answer to your question is:

1 and 27

Below we illustrate and prove that 1 and 27 multiply to 27 and add up to 28:

1 × 27 = 27
1 + 27 = 28

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

x² + 28x + 27 = 0

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

(x + 1 ) (x + 27)

To summarize, since 1 and 27 multiply to 27 and add up 28, you know that the following is true:

x² + 28x + 27 = (x + 1 ) (x + 27)
