What is the standard form of a polynomial #(5x - 5)(2x - 4)#?

Let the expression be labelled as #p(x) = (5x - 5)(2x - 4)#

Performing a multiplication,

#p(x) = 5*2x^2 -4*5x -5*2x +5*4#
#implies p(x) = 10x^2 + x(-20 - 10) + 20#

Thus, we get,

#p(x) = 10x^2 - 30x + 20# which is in the standard form of a two degree polynomial.
