Answer 1

$341) \\ {a}^{4} + 2 {a}^{2} = {a}^{2} ( {a}^{2} + 2) \\ {a}^{4} - 3 {a}^{3} = {a}^{3} (a - 3) \\ {a}^{4} {b}^{2} + a {b}^{3} = a {b}^{2} ( {a}^{3} + b) \\ {x}^{2} {y}^{3} - {x}^{3} {y}^{2} = {x}^{2} {y}^{2} (y - x)$

$342) \\ 18 {y}^{7} + 12 {y}^{4} = 6 {y}^{4} (3 {y}^{3} + 2) \\ 6 {x}^{4} - 24 {x}^{2} = 6 {x}^{2} ( {x}^{2} - 4) \\ 15 {x}^{5} - 5 {x}^{3} = 5 {x}^{3} (3 {x}^{2} - 1) \\ 6 {a}^{5} + 3 {a}^{2} = 3 {a}^{2} (2 {a}^{3} + 1)$

$343) \\ 9 {a}^{2} {b}^{2} - 12a {b}^{3} = 3a {b}^{2} (3a - 4b) \\ 20 {x}^{3} {y}^{2} + 4 {x}^{2} y = 4 {x}^{2} y(5xy + 1) \\ 7 {a}^{2} bc + 14a {b}^{2} c = 7abc(a + 2b) \\ 9xy {z }^{2} - 12x {y}^{2} z = 3xy(3z - 4y)$
