What two numbers multiply to 426 and add up to 427?

Here we answer the question: "What two numbers multiply to 426 and add up to 427?"

The answer to your question is:

1 and 426

Below we illustrate and prove that 1 and 426 multiply to 426 and add up to 427:

1 × 426 = 426
1 + 426 = 427

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

x² + 427x + 426 = 0

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

(x + 1 ) (x + 426)

To summarize, since 1 and 426 multiply to 426 and add up 427, you know that the following is true:

x² + 427x + 426 = (x + 1 ) (x + 426)
