Trying to find the right answer to this..

p 2 - 8p + 16 = (p) 2 - 2(4)(p) + (4) 2 = (p - 4) 2 [Using a 2 + b 2 - 2ab = (a -b) 2 ] = (p - 4) (p - 4) Thus, p 2 - 8p + 16 = (p - 4)(p - 4)

Factorise:
p² - 8p + 16

p² - 8p + 16 = (p)² - 2(4)(p) + (4)²

                  = (p - 4)² [Using a² + b² - 2ab = (a -b)²]

                  = (p - 4) (p - 4)

   Thus, p² - 8p + 16 = (p - 4)(p - 4)
