To find the solutions of this equation we can divide all the expression by 3:
[tex]\begin{gathered} 3x^2+6x-24=0 \\ x^2+2x-8=0 \end{gathered}[/tex]
Now, factor the expression:
[tex](x+4)(x-2)=0[/tex]
Make each factor equal to 0 and find x:
[tex]\begin{gathered} x+4=0 \\ x=-4 \\ x-2=0 \\ x=2 \end{gathered}[/tex]
It means that the solutions are -4 and 2. The correct answer is the last choice.
