What two numbers multiply to -213 and add up to -212?

Here we answer the question: "What two numbers multiply to -213 and add up to -212?"

The answer to your question is:

-213 and 1

Below we illustrate and prove that -213 and 1 multiply to -213 and add up to -212:

-213 × 1 = -213
-213 + 1 = -212

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

x² - 212x - 213 = 0

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

(x - 213 ) (x + 1)

To summarize, since -213 and 1 multiply to -213 and add up -212, you know that the following is true:

x² - 212x - 213 = (x - 213 ) (x + 1)
