G = - 6 x² - 12 x
H = 6 x ³ - 10 x² - 28 x² + 21 x
= 6 x ³ - 38 x² + 21 x
I = 6 a² + 8 ab - 4 a - 10 ab + 15 b² - 20 b
= 6 a² - 4 a - 2 ab + 15 b² - 20 b
J = - 14 x ⁵ + 28 x ⁴ + 24 x ⁵ - 48 x ⁴ + 8 x² = 10 x ⁵ - 20 x ⁴ + 8 x²
K = 10 x ³ + 6 x² - 16 x - 20 x² - 12 x + 32
= 10 x ³ - 14 x² - 28 x + 32
L = ( - 10 x² + 6 x + 20 x - 12 ) ( 3 x - 5 )
= ( - 10 x² + 26 x - 12 ) ( 3 x - 5 )
= - 30 x ³ + 50 x² + 78 x² - 130 x - 36 x + 60
= - 30 x ³ + 128 x² - 166 x + 60
