What two numbers multiply to 488 and add up to 489?

Here we answer the question: "What two numbers multiply to 488 and add up to 489?"

The answer to your question is:

1 and 488

Below we illustrate and prove that 1 and 488 multiply to 488 and add up to 489:

1 × 488 = 488
1 + 488 = 489

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

x² + 489x + 488 = 0

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

(x + 1 ) (x + 488)

To summarize, since 1 and 488 multiply to 488 and add up 489, you know that the following is true:

x² + 489x + 488 = (x + 1 ) (x + 488)
