(2x + 1) {}^{3}  + (2x - 1) {}^{3}
apply \: a {}^{3}   +  b {}^{3}  = (a  +  b)(a {}^{2}  + ab + b {}^{2} )

(2x + 1  +  2x + 1)(2x + 1) {}^{2} + (2x + 1)(2x - 1) + (2x - 1) {}^{2}

(4x + 2)(4x {}^{2}  + 4x + 1 + 4x {}^{2} - 1 + 4x {}^{2}   - 4x  - 1)


(4x + 2)12 {x}^{2}

48x {}^{3}  + 24x {}^{2}


Thanks
