Answer 1

( 3 ) : ( ii )


{ ( x³ + 1 ) / ( x⁴ + 1 ) } × { ( x³ - 1 ) / ( x⁴ - 1 ) }


[ { x³ + 1 }{ x³ - 1 } ] / [ { x⁴ + 1 }{ x⁴ - 1 } ]


$\dfrac{x^{6}-1}{x^{8}-1}$



$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \mathsf{ Or}$


[ {x³+1}/{x⁴+1]×[{x³-1}{x⁴-1}]


[(x+1)(x²-x+1)/(x⁴+1)]×[(x-1)(x²+x+1)/(x²-1)(x²+1)]


[(x+1)(x²-x+1)/(x⁴+1)]×[(x-1)(x²+x+1)/(x-1)(x+1)(x²+1)]


[x²-x+1/x⁴+1 ] × [x²+x+1/x²+1]


[(x+1)²-x²]×[x^{6}+x⁴+x²+1]




4 : ( ii )

[(6x²+3x-2x-1)/(2x²-10x+3x-15)]×[(4x²-9)/(4x²+4x+1)]


[ {3x(2x+1)-(2x+1)}/{2x(x-5)+3(x-5)}]×[{(2x)²-(3)³}/{(2x+1)²]


[{(2x+1)(3x-1)}/{(x-5)(2x+3)}]×[{(2x+3)(2x-3)}/{(2x+1)}]


[(3x-1)/(x-5)]×[(2x-3)/(2x+1)]


$\dfrac{6 {x}^{2} - 11x + 3}{2 {x}^{2} - 9x - 5}$
