Explicación paso a paso:

1.

$(3a+6)^{2} =(3a+6)(3a+6)$$=9a^{2} +18a+18a+36=9a^{2} +36a+36$

2.

$(a-b)^{2} =(a-b)(a-b)=a^{2} -ab-ab+b^{2} =a^{2}-2ab+b^{2}$

3.

$(5x-8)^{2}= (5x-8)(5x-8)=25x^{2} -40x-40x+64=25x^{2} -80x+64$

4.

$(4m+3n)^{2} =(4m+3n)(4m+3n)=16m^{2} +12mn+12mn+9n^{2} =16m^{2} +24mn+9n^{2}$

5.

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

6.

$(3b+4)^{2} =(3b+4)(3b+4)=9b^{2} +12b+12b+16=9b^{2} +24b+16$

7.

$(3x-2)^{2} =(3x-2)(3x-2)=9x^{2} -6x-6x+4=9x^{2} -12x+4$

8.

$(2a+1)^{2} =(2a+1)(2a+1)=4a^{2} +2a+2a+1=4a^{2}+4a+1$

9.

$(3a+6)^{2} =(3a+6)(3a+6)=9a^{2} +18a+18a+36=9a^{2} +36a+36$

10.

$(a+b)^{2} =(a+b)(a+b)=a^{2} +ab+ab+b^{2} =a^{2} +2ab+b^{2}$
