[tex](a + 2 {)}^{2} = {a}^{2} + 4a + 4 \\ (6 - x {)}^{2} = 36 - 12x + {x}^{2} \\ (3x - 4 {)}^{2} = 9 {x}^{2} - 24x +16 \\ (0.1a + 10b {)}^{2} = 0.01 {a}^{2} + 2ab + 100 {b}^{2} \\ (5m + 3n {)}^{2} = 25 {m}^{2} + 30mn + 9 {n}^{2} \\ (5 {a}^{4} - 2 {a}^{2} {b}^{4} {)}^{2} = 25 {a}^{8} - 20 {a}^{6} {b}^{4} + 4 {a}^{4} {b}^{8} \\ ( {x}^{4} - {x}^{2} {)}^{2} = {x}^{8} - 2 {x}^{6} + {x}^{4} \\(6x - \frac{1}{3} y {)}^{2} = 36 {x}^{2} - 4xy + \frac{1}{9} {y}^{2} [/tex]
