What two numbers multiply to -140 and add up to 68?




Here we answer the question: "What two numbers multiply to -140 and add up to 68?"

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 68:

-2 × 70 = -140
-2 + 70 = 68

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

x2 + 68x - 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 68, you know that the following is true:

x2 + 68x - 140 = (x - 2 ) (x + 70)
