(i)4x^2+9y^2+25z^2+12xy+30yz+20+xz.

(a+b+c)^2=a^2+b^2+c^2+2ab+2bc+2ca

(2 x)^{2}+(3 y)^{2}+(5 z)^{2}+2(2 x)(3 y)+2(3 y)(5 z)+2(2 x)(5 z)

=(2 x+3 y+5 z)^{2}

(ii) 25 x^{2}+4 y^{2}+9 z^{2}-20 x y+12 y z-30 x z

(a+b+c)^2=a^2+b^2+c^2+2ab+2bc+2ca

(5 x)^{2}+(2 y)^{2}+(3 z)^{2}-2(5 x)(2 y)+2(2 y)(3 z)-2(5 x)(3 z)

=(-5 x+2 y+3 z)^{2} அல்லது  (5 z-2 y-3 z)^{2}
