Упростите выражения:(2х-1)²(2+3в)²(х³-3)²

(2х-1)²=(2x)^2-2*2x*1+1^2=4x^2-4x+1 =============================== (2+3b)²=2^2+2*2*3b+(3b)^2=4+12b+9b^2 =============================== (х³-3)²=(x^3)^2-2x^3*2+2^2=x^6-4x^3+4 ===============================

(2x-1)^2=4x^2-4x+1 (2+3b)^2=4+12b+9b^2 (x^3-3)=x^9-6x^3+9
