(3x^2-3y^2)2
=[(3x+2y)(3x-2y)]2
=(9x^2-6xy+6xy-4y^2)2
Its the expanded form

Now,the simplified form is
=(9x^2-6xy+6xy-4y^2)2
=(9x^2-4y^2)2
=18x^2+8y^2
=[(3x+2y)(3x-2y)]2
=(9x^2-6xy+6xy-4y^2)2
Its the expanded form

(3x²-2y²)²=(3x²)²-2×3x²×2y²+(2y²)²
=9x²×²-12x²y²+4y²×²
=9x4-
=9x²×²-12x²y²+4y²×²
=9x4-
