(5 + x )2
(x – y )2
(1 – 3x2 )2
(4m5 – 5n6 )2
(7c2 d2+ 5x2 )2
(3/2 x2 – 3y2)2

Answer 1

Explicación paso a paso:

${(5 + x) }^{2} = {5}^{2} + 2(5)(x) + {x}^{2} = 25 + 10x + {x}^{2}$

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

${(1 - 3{x}^{2} )}^{2} = {1}^{2} - 2(1)( {3x}^{2} ) + {(3 {x}^{2} )}^{2} = {1}^{2} - 6 {x}^{2} + 9 {x}^{4}$

${(4 {m}^{5} - 5 {n}^{6} )}^{2} = {(4 {m}^{5} )}^{2} - 2(4 {m}^{5} )(5 {n}^{6} ) + {(5 {n}^{6} )}^{2} = 16 {m}^{10} - 40 {m}^{5} {n}^{6} + 25 {n}^{6}$

${(7 {c}^{2} {d}^{2} + 5 {x}^{2}) }^{2} = 49 {c}^{4} {d}^{4} + 70{c}^{2} {d}^{2} {x}^{2} + 25 {x}^{4}$

${( \frac{3 {x}^{2} }{2} - 3 {y}^{2} )}^{2} = \frac{9 {x}^{4} }{4} - 9 {x}^{2} {y}^{2} + 9 {y}^{4}$
