What two numbers multiply to 420 and add up to 212?

Here we answer the question: "What two numbers multiply to 420 and add up to 212?"

The answer to your question is:

2 and 210

Below we illustrate and prove that 2 and 210 multiply to 420 and add up to 212:

2 × 210 = 420
2 + 210 = 212

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

x² + 212x + 420 = 0

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

(x + 2 ) (x + 210)

To summarize, since 2 and 210 multiply to 420 and add up 212, you know that the following is true:

x² + 212x + 420 = (x + 2 ) (x + 210)
