What two numbers multiply to 140 and add up to 72?

Here we answer the question: "What two numbers multiply to 140 and add up to 72?"

The answer to your question is:

2 and 70

Below we illustrate and prove that 2 and 70 multiply to 140 and add up to 72:

2 × 70 = 140
2 + 70 = 72

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

x² + 72x + 140 = 0

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

(x + 2 ) (x + 70)

To summarize, since 2 and 70 multiply to 140 and add up 72, you know that the following is true:

x² + 72x + 140 = (x + 2 ) (x + 70)
