A)=3 x^{2} +1- x^{2} +6x+9=2 x^{2} +6x+10
b)=(3 x^{2} )+2*3x*5+5 ^{2} -x ^{2} +2*x*1+1 ^{2} =9 x^{2} +30x+25- x^{2} +2x+1=8 x^{2} +32x+26
c)= x^{2} +2*x* \sqrt{2}+ (\sqrt{2}) ^{2} -8= x^{2} +2 \sqrt{2}x+2-8= x^{2} +2 \sqrt{2}x-6
d)=(2 x)^{2} +2*2x* \sqrt{3}+( \sqrt{3})^{2} =4x ^{2}+4 \sqrt{3}x+3
e)=( \sqrt{2} ) ^{2} -2* \sqrt{2} *1+1 ^{2} -32 x^{2} =2-2 \sqrt{2} +1-32 x^{2} =3-2 \sqrt{2} -32 x^{2}
