Răspuns:

a) 3a^3-15a^2b+5ab^2 =3a(a^2-5ab+5a^2b^2/3)

b)20x^4-25x^2y^2-10x^3=5x^2(4x^2-5y^2-2x)

c)-6am^2+9m^3-12m^4=3m^2(-2a+3m-4m^2)

d)12a^2b-18ab^2-30ab^3=6ab(2a-3b-5b^2)

e)4ax^3+8a^x^2-12a^3*x=4ax(x^2+2x-3a^2)

f)-3x^4y^2-6x^2*y^2+9x^y^4= -3x^2y^2(3x^2+2-3y^2)

g)10a^2*x-15a^3*x^2-20a^4*x=5a^2*x(2-3ax-4a^2)

h)8a^4*b^3-32a^2*b^4+16a^3*b^2=8a^2*b^2(a^2*b-4b^2+2a)
