Explicación paso a paso:

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

$( x-5)^{2} =x^{2} -10x+25$

$(x+3)^{2} +(x-3)^{2} =2x^{2} +18$

$(x+2)^{2} +(x-2)^{2} =2x^{2} +8$

$(2x+y)^{2}+(2x-y)^{2} =8x^{2} +2y^{2}$

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

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

$(x^{2}+5)(x^{2} -5)=x^{4}-25$

$(x+3)(x+4)=x^{2} +7x+12$

$(x-4)(x-5)=x^{2} -9x+20$

$(x+2)(x-4)=x^{2} -2x-8$

$(x^{2} +5)(x^{2} -3)=x^{4}+2x^{2} -15$
