We have to factorize the expression by grouping. The expression is: - 8 x^3 - 2 x^2 - 12 x - 3. We can group this expression like this: ( - 8 x^3 - 2 x^2 ) + ( - 12 x - 3 ) = ( - 2 x^2 ) ( 4 x + 1 ) + ( - 3 ) ( 4 x + 1 ) = ( 4 x + 1 ) ( - 2 x^2 - 3 ) = - ( 4 x + 1 ) ( 2 x^2 + 3 ). Answer: The resulting expression is: - ( 4 x + 1 ) * ( 2 x^2 + 3 ).
