Question

Подати у вигляді многочлена
(c + d) 2
(х − у) 2
(5 + а) 2
(3с −d) 2
(а 2 − 3b) 2
(2х + 5у 3) 2
(а 5 − 1) 2
(4c 2d− 5с)

Answer 1

${(c + d)}^{2} = {c}^{2} + 2cd + {d}^{2} \\ {(x - y)}^{2} = {x}^{2} - 2xy + {y}^{2} \\ {(5 + a)}^{2} = 25 + 10a + {a}^{2} \\ {(3c - d)}^{2} = {9c}^{2} - 6cd + {d}^{2} \\ {( {a}^{2} - 3b) }^{2} = {a}^{4} - 6 {a}^{2} b + {9b}^{2} \\ {(2x + 5 {y}^{3} })^{2} = {4x}^{2} + {20xy}^{3} + 25 {y}^{6} \\ {( {a}^{5} - 1) }^{2} = {a}^{10} - 2 {a}^{5} + 1 \\ {(2d - 5c)}^{2} = {4d}^{2} - 20dc + {25c}^{2}$
