What two numbers multiply to 8 and add up to 6?

Here we answer the question: "What two numbers multiply to 8 and add up to 6?"

The answer to your question is:

2 and 4

Below we illustrate and prove that 2 and 4 multiply to 8 and add up to 6:

2 × 4 = 8
2 + 4 = 6

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

x² + 6x + 8 = 0

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

(x + 2 ) (x + 4)

To summarize, since 2 and 4 multiply to 8 and add up 6, you know that the following is true:

x² + 6x + 8 = (x + 2 ) (x + 4)
