What two numbers multiply to -180 and add up to 88?

Here we answer the question: "What two numbers multiply to -180 and add up to 88?"

The answer to your question is:

-2 and 90

Below we illustrate and prove that -2 and 90 multiply to -180 and add up to 88:

-2 × 90 = -180
-2 + 90 = 88

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

x² + 88x - 180 = 0

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

(x - 2 ) (x + 90)

To summarize, since -2 and 90 multiply to -180 and add up 88, you know that the following is true:

x² + 88x - 180 = (x - 2 ) (x + 90)
