Answer 1

$1) {b}^{2} - 2b + 1 = {(b - 1)}^{2}$

$2)4 + 4n + {n}^{2} = {(2 + n)}^{2}$

$3) {x}^{2} - 14x + 49 = {(x - 7)}^{2}$

$4)4 {a}^{2} + 4ab + {b}^{2} = {(2a + b)}^{2}$

$5)9 {x}^{2} - 24xy + 16 {y}^{2} = {(3x - 4y)}^{2}$

$6) {a}^{6} - 2 {a}^{3} + 1 = {( {a}^{3} - 1)}^{2}$

$7)36 {a}^{6} - 84 {a}^{3} {b}^{5} + 49 {b}^{10} = {(6 {a}^{3} - 7 {b}^{5} )}^{2}$

$8)81 {x}^{4} {y}^{8} - 36 {x}^{2} {y}^{4} {z}^{6} + 4 {z}^{12} = {(9 {x}^{2} {y}^{4} - 2 {z}^{6} )}^{2}$
