`(2x-3)^3-(2x+3)(4x^2-1) = -24`
`⇔ 8x^3-36x^2+54x-27-8x^3+2x-12x^2+3+24 = 0`
`⇔ (8x^3-8x^3)-(36x^2+12x^2)+(54x+2x)+(-27+3+24) = 0`
`⇔ -48x^2+56x = 0`
`⇔ -8x(6x-7)=0`
`⇔` \(\left[ \begin{array}{l}-8x=0\\6x-7=0\end{array} \right.\)
`⇔` \(\left[ \begin{array}{l}x=0\\6x=7\end{array} \right.\)
`⇔` \(\left[ \begin{array}{l}x=0\\x=\dfrac{7}{6}\end{array} \right.\)
`\text{Vậy}` `x=0` `\text{hoặc}` `x=7/6`
