Question 1131327


{{{(a^2-6)^2-(4a+6)^2 }}}

{{{a^4 - 12 a^2 + 36-(16 a^2 + 48 a + 36)}}}

{{{a^4 - 12 a^2 + 36-16 a^2 - 48 a - 36}}}

{{{a^4 - 28 a^2 - 48 a}}}

{{{a(a^3 - 28 a - 48 )}}}

{{{a(a^3-6a^2+6a^2-36a+8a - 48 )}}}

{{{a((a^3-6a^2)+(6a^2-36a)+(8a - 48) )}}}

{{{a(a^2(a-6)+6a(a-6)+8(a - 6) )}}}

{{{a((a^2+6a+8)(a - 6) )}}}

{{{a((a^2+2a+4a+8)(a - 6) )}}}

{{{a((a^2+2a)+(4a+8))(a - 6) )}}}

{{{a(a(a+2)+4(a+2))(a - 6) )}}}

{{{a(a + 2) (a - 6)  (a + 4)}}}
