Step 01

Data :

(3x - 8) ²

Step 02

(3x - 8) ²

(3x - 8) (3x - 8)

9x² - 24x - 24x + 64

9x² - 48x + 64

Sum.

(9x² - 48x + 64) +( 9x² - 48x + 64)

18x² - 96x + 128

Product.

(9x² - 48x + 64) * ( 9x² - 48x + 64)


81x^4-432x^(3)\text{ + }576x^(2)\text{ -}432x^3\text{ + }2304x^(2)-3072x+576x^2-3072x+4096
81^4-864x^3+3456x^(2)-6144x^{}^{}+4096
