Answer 1

$a) \: (x + 5)^{2} = {(x)}^{2} + 2(x)(5) + {(5)}^{2} \\ \boxed{ \boxed{ {(x + 5)}^{2} = {x}^{2} + 10x + 25}}$

$b) \: {(2x + 1)}^{2} = {(2x)}^{2} + 2(2x)(1) + {(1)}^{2} \\ \boxed{ \boxed{{(2x + 1)}^{2} = {4x}^{2} + 4x + 1}}$

$c) \: {( {x}^{2} + 2)}^{2} = {( {x}^{2}) }^{2} + 2( {x}^{2} )(2) + {(2)}^{2} \\ \boxed{ \boxed{({x}^{2} + 2)^{2} = {x}^{4} + 4 {x}^{2} + 4}}$

$c) \: {( {5x}^{3} + 3)}^{2} = ( {5x}^{3} )^{2} + 2( {5x}^{3} )(3) + {(3)}^{2} \\ \boxed{ \boxed{ ( {5x}^{3} + 3 )^{2} = 25 {x}^{6} + 30 {x}^{3} + 9}}$
