What two numbers multiply to -144 and add up to -70?

Here we answer the question: "What two numbers multiply to -144 and add up to -70?"

The answer to your question is:

-72 and 2

Below we illustrate and prove that -72 and 2 multiply to -144 and add up to -70:

-72 × 2 = -144
-72 + 2 = -70

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

x² - 70x - 144 = 0

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

(x - 72 ) (x + 2)

To summarize, since -72 and 2 multiply to -144 and add up -70, you know that the following is true:

x² - 70x - 144 = (x - 72 ) (x + 2)
