The factored form of the polynomial z^2 -10z + 25 is ( z -5 ) ( z - 5 )
polynomials are expressions which are made up of variables related with mathematical operations, the variables usually have index starting from 2.
while factored form implies factorization
Given data
z^2 -10z + 25
Solving the polynomial we have
z^2 -10z + 25
z^2 -5z - 5z + 25
( z^2 -5z ) - ( 5z + 25 )
z ( z -5 ) - 5 ( z - 5 )
( z -5 ) ( z - 5 )
