What two numbers multiply to 420 and add up to 143?

Here we answer the question: "What two numbers multiply to 420 and add up to 143?"

The answer to your question is:

3 and 140

Below we illustrate and prove that 3 and 140 multiply to 420 and add up to 143:

3 × 140 = 420
3 + 140 = 143

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

x² + 143x + 420 = 0

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

(x + 3 ) (x + 140)

To summarize, since 3 and 140 multiply to 420 and add up 143, you know that the following is true:

x² + 143x + 420 = (x + 3 ) (x + 140)
