Question

помогите пожалуйста

Answer 1

Ответ:

$(2a + 1) ^{2} = 4 {a}^{2} + 4a + 1$

$(2x - 3)^{2} = 4 {x}^{2} - 12x + 9$

${(2 - 2z)}^{2} = 4 - 8z + 4 {z}^{2}$

$(3y + 1) ^{2} = 9 {y}^{2} + 6y + 1$

$(1 - 3y) ^{2} = 1 - 6y + 9 {y}^{2}$

$(3 + 2x) ^{2} = 9 + 12x + 4 {x}^{2}$

$(4a + 3b) ^{2} = 16 {a}^{2} + 24ab + 9 {b}^{2}$

$(4z + 5) ^{2} = 16 {z}^{2} + 40z + 25$

$(6u - 5v) ^{2} = 36 {u}^{2} - 60uv + 25 {v}^{2}$

$(2x - 7y) ^{2} = 4 {x}^{2} - 28xy + 28 {y}^{2}$

$(8 - 2u) ^{2} = 64 - 32u + 4 {u}^{2}$

$(8s + 3t) ^{2} = 64 {s}^{2} + 48st + 9 {t}^{2}$
