What two numbers multiply to -143 and add up to 142?

Here we answer the question: "What two numbers multiply to -143 and add up to 142?"

The answer to your question is:

-1 and 143

Below we illustrate and prove that -1 and 143 multiply to -143 and add up to 142:

-1 × 143 = -143
-1 + 143 = 142

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

x² + 142x - 143 = 0

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

(x - 1 ) (x + 143)

To summarize, since -1 and 143 multiply to -143 and add up 142, you know that the following is true:

x² + 142x - 143 = (x - 1 ) (x + 143)
