We use Vieta's formulas to find the product of the roots. For \( h(x) = 2x^3 - 9x^2 + 12x - 4 \), the product of all roots is \( -d/a = -(-4)/2 = 2 \). Assuming the roots \( r_1, r_2, r_3 \) include a non-zero root \( r_1 \) and potentially zero roots, we check if zero is a root by substituting \( x = 0 \). Since \( h(0) = -4
