What two numbers multiply to 400 and add up to 58?

Here we answer the question: "What two numbers multiply to 400 and add up to 58?"

The answer to your question is:

8 and 50

Below we illustrate and prove that 8 and 50 multiply to 400 and add up to 58:

8 × 50 = 400
8 + 50 = 58

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

x² + 58x + 400 = 0

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

(x + 8 ) (x + 50)

To summarize, since 8 and 50 multiply to 400 and add up 58, you know that the following is true:

x² + 58x + 400 = (x + 8 ) (x + 50)
