What two numbers multiply to 416 and add up to 42?

Here we answer the question: "What two numbers multiply to 416 and add up to 42?"

The answer to your question is:

16 and 26

Below we illustrate and prove that 16 and 26 multiply to 416 and add up to 42:

16 × 26 = 416
16 + 26 = 42

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

x² + 42x + 416 = 0

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

(x + 16 ) (x + 26)

To summarize, since 16 and 26 multiply to 416 and add up 42, you know that the following is true:

x² + 42x + 416 = (x + 16 ) (x + 26)
