What two numbers multiply to 280 and add up to 142?

Here we answer the question: "What two numbers multiply to 280 and add up to 142?"

The answer to your question is:

2 and 140

Below we illustrate and prove that 2 and 140 multiply to 280 and add up to 142:

2 × 140 = 280
2 + 140 = 142

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

x² + 142x + 280 = 0

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

(x + 2 ) (x + 140)

To summarize, since 2 and 140 multiply to 280 and add up 142, you know that the following is true:

x² + 142x + 280 = (x + 2 ) (x + 140)
