In the first step, the error is in distributing the products

result: $3x^{2}-2x-8$
Work Step by Step
In the first step, the error is in distributing the products
(one term is missing, there should be four).
It should be
$(x-2)(3x+4)$
$=x(3x)+x(4)-2(3x)-2(4)$
$=3x^{2}+4x-6x-8$
...add like terms.
=$3x^{2}-2x-8$
