Explicación paso a paso:

1) $(3x - 2y)^{2} = (3x)^{2} - 2(3x)(2y) + (2y)^{2} = 9x^{2} - 12xy + 4y^{2}$

2) $(x +y)^{2} = x^{2} + 2xy +y^{2}$

3) $(3x-2)^{2} = (3x)^{2} -2(3x)(2) +2^{2} = 9x^{2} - 12x + 4$

4) $(4x + 2y)x^{2} = (4x)^{2}+ 2(4x)(2y) + (2y)^{2} = 16x^{2} + 16xy+4y^{2}$

5) $(x-y)^{2} = x^{2} - 2xy + y^{2}$

6) $(2x-y)^{2} = (2x)^{2} -2(2x)(y) + y^{2} = 4x^{2} - 4xy + y^{2}$

7) $(2x+y)^{2} = (2x)^{2} +2(2x)(y) + y^{2} = 4x^{2} + 4xy + y^{2}$

   8)  $(5x^{2} y + 3x^{2} )^{2} = (5x^{2} y)^{2} + 2(5x^{2} y)(3x^{2} ) +(3x^{2} )^{2} \\ = 25x^{4}y^{2} + 30x^{4} y + 9x^{4}$

9) $(4x^{4}-6y^{3}) ^{2} = (4x^{4} )^{2} - 2(4x^{4} )(6(y^{3} )+ (6y^{3}) ^{2} = 16x^{8} -48x^{4} y^{3} + 36y^{6}$

10) $(y^{2}- 2x) ^{2} = (y^{2})^{2} - 2(y^{2})(2x) + (2x)^{2} = y^{4} - 4xy + 4x^{2}$
