Find the factorization of the polynomial below.

81x2 - 18x + 1

(9x-1) ²

Step-by-step explanation:

81x² - 18x + 1 = (9x) ² - 2*9x+1² = (9x-1) ²

(9x - 1) ²

Step-by-step explanation:

If you can tell, the square root of 81 is 9. This should be a clue that the polynomial could be one binomial squared. If you tried factoring starting out with 9x in both parenthesis, you could see that you would get (9x - 1) ² as your answer.
