(I)2mn×3m=m(2n×3).

hope this May help you

Answer 2

Answer:

$2mn \times 3m = 6 {m}^{2} n \\ \\ \\ - 2ab \times 6ab = - 12 {a}^{2} {b}^{2} \\ \\ \\ xy \times ( - 5 {x}^{2} y) = - 5 {x}^{3} {y}^{2} \\ \\ \\ (x + 2)(x + 4) = {x}^{2} + 4x + 2x + 8 = \\ \\ {x}^{2} + 6x - 8 \\ \\ \\ \\( a + 2)(a - 3) = \\ {a}^{2} - 3a + 2a - 6 \\ = { {a}^{2} - a - 6}^{2} \\ \\ \\(2a + b)(a - 3b) \\ \\ \\ 2 {a}^{2} - 6ab + ab - 3 {b}^{2} \\ 2 {a}^{2} - 3 {b}^{2} - 6ab$

Hope that it will help you....
