$$\eqalign{&x^2-10x+16=0 \
                 &(x^2-10x)+16=0 \
                 &(x^2-10x+25-25)+16=0 \
                 &(x^2-10x+25)+16-25=0 \
                 &(x-5)^2-9=0 \
                 &(x-5)^2=9 \
                 &\sqrt{(x-5)^2}=\pm\sqrt{9} \
                 &x-5=\pm 3 \
                 &x=\pm3+5 \
                 &x=5\pm 3 \
                 &(x=5+3) or(x=5-3) \
                 &(x=8)or(x=2)\}$$
