Question

product (x^2-1)(x^4+x^2+1)​

Answer 1

$\huge \sf \underline \pink{Answer : }$

$\sf \purple{ \implies \: {x}^{6} - 1 }$

$\sf \huge \underline \red{Given : }$

• product (x²-1)(x⁴+x²+1)

$\sf \huge \underline \blue{solution : }$

$\: \: \: \: \: \: \: \: \: \sf{(x²-1)(x⁴+x²+1)}$

$\sf \underline{we \: know \: that \: identity : }$

$\sf \underline \red{( {a}^{3} - {b}^{3} ) = (a - b)( {a}^{2} + ab + {b}^{2})}$

$\: \: \: \: \: \: \: \: \: \sf{(x²-1)(x⁴+x²+1)}$

$\sf{ \implies \: ( {x}^{2} - 1)(( {x}^{2}) {}^{2} + {x}^{2} (1) + {1}^{2} )}$

$\sf{ \implies \: ( (( {x}^{2}) {}^{3} - {1}^{3} )}$

$\sf{ \implies \: {x}^{6} - 1 }$
