What two numbers multiply to 169 and add up to -26?

Here we answer the question: "What two numbers multiply to 169 and add up to -26?"

The answer to your question is:

-13 and -13

Below we illustrate and prove that -13 and -13 multiply to 169 and add up to -26:

-13 × -13 = 169
-13 + -13 = -26

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

x² - 26x + 169 = 0

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

(x - 13 ) (x - 13)

To summarize, since -13 and -13 multiply to 169 and add up -26, you know that the following is true:

x² - 26x + 169 = (x - 13 ) (x - 13)
