Find the product of:

(i) \((2x + 3)(2x - 4) =\)

(ii) \((y^2 - 4)(2y^2 + 3y) =\)

(iii) \((m^2 - n)(5m^2n^2 - n^2) =\)

(iv) \(3(x - 5) \times 2(x - 1) =\)

Answer variants:

{5 m}^{4} n^{2} - m^{2} n^{2} + {5 m}^{2} n^{3} + n^{3}

{5 m}^{4} n^{2} - m^{2} n^{2} - {5 m}^{2} n^{3} + n^{3}

{2 y}^{4} + {3 y}^{3} - {8 y}^{2} - 12 y

{4 x}^{2} - 2 x - 12

{6 x}^{2} + 36 x + 30

{2 y}^{4} + {3 y}^{3} - {8 y}^{2} + 12 y

{6 x}^{2} - 36 x + 30

{4 x}^{2} + 2 x - 12
