What two numbers multiply to 420 and add up to -143?

Here we answer the question: "What two numbers multiply to 420 and add up to -143?"

The answer to your question is:

-140 and -3

Below we illustrate and prove that -140 and -3 multiply to 420 and add up to -143:

-140 × -3 = 420
-140 + -3 = -143

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

x² - 143x + 420 = 0

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

(x - 140 ) (x - 3)

To summarize, since -140 and -3 multiply to 420 and add up -143, you know that the following is true:

x² - 143x + 420 = (x - 140 ) (x - 3)
