What two numbers multiply to -288 and add up to 142?

Here we answer the question: "What two numbers multiply to -288 and add up to 142?"

The answer to your question is:

-2 and 144

Below we illustrate and prove that -2 and 144 multiply to -288 and add up to 142:

-2 × 144 = -288
-2 + 144 = 142

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

x² + 142x - 288 = 0

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

(x - 2 ) (x + 144)

To summarize, since -2 and 144 multiply to -288 and add up 142, you know that the following is true:

x² + 142x - 288 = (x - 2 ) (x + 144)
