Explicación paso a paso:

1 ) $(X+8)^{2}= x^{2} +2 ( X) (8) +8^{2}= x^{2}+16X +64$

2) $(x-7)^{2}=x^{2} - 2(X)(7) +7^{2}= x^{2} -14X +49$

3)$(3x+5)^{2}= (3x)^{2}+2(3X)(5)+5^{2}= 9x^{2}+30X +25$

4) $(3-x)^{2}= 3^{2}-2(3)(X)+x^{2} = 9-6X+x^{2}$

5) $(\frac{x}{2}+\frac{Y}{3} )^{2} = (\frac{x}{2}) ^{2} +(\frac{Y}{3})^{2}+2(\frac{X}{2} )(\frac{Y}{3} )= \frac{x^{2} }{4}+\frac{Y^{2} }{9}+\frac{xy}{3}$

6)(x-7)(x+7) = $x^{2} -7^{2}$
