1. a*(x-1)^3 – (x-3)*(x^2 +3*x+9) * b*(4*x-1)^3 – (4*x-3)*(16*x^2 +3)

   -64*b*x^6+48*b*x^5-12*b*x^4+(1729*b+a-64)*x^3+(-1296*b-3*a+48)*x^2+(324*b+3*a-12)*x-27*b-a+9

   -(64*b*x^6-48*b*x^5+12*b*x^4-1729*b*x^3-a*x^3+64*x^3+1296*b*x^2+3*a*x^2-48*x^2-324*b*x-3*a*x+12*x+27*b+a-9)

   b*(4 *x-1)^3 – (4 *x-3)*(16 *x^2 + 3)

   (64*b-64)*x^3+(48-48*b)*x^2+(12*b-12)*x-b+9

   64*b*x^3-64*x^3-48*b*x^2+48*x^2+12*b*x-12*x-b+9
