Question

помогите пожалуйста ​

Answer 1

$(m + 2)(m + 2) = m \times m + m \times 2+ 2 \times m + 2 \times 2 = {m}^{2} + 4m + 4 \\ (3 + p)(3 + p) = 3 \times 3 + 3 \times p + p \times 3 + p \times p = 9 + 6p + {p}^{2} \\ (2a + b)(2a + b) = 2a \times 2a + 2a \times b + b \times 2a + b \times b = {4a}^{2} + 4ab + {b}^{2} \\ (5 + c)(5 + c) = 5 \times 5 + 5 \times c + c \times 5 + c \times c = 25 + 10c + {c}^{2}$
